Disable User Account Control In Windows 10

On Microsoft Windows 10, User Account Control ('UAC') prevents applications from making certain changes on your PC. Some applications try to change system-related parts, such as the Registry or the file system.

ML Bot is one of these applications because, in order to manage Magic Online and uninstall / reinstall it, the bot needs to access the file system (the "files on your hard drive"). If you don't disable UAC, ML Bot will not be able to perform certain tasks on Magic Online and in particular to repair MTGO in case of crash. As result the bot will work fine until MTGO crashes. At this point ML Bot will not be able to handle the crash and recover.
Please note that on a stable machine this will hardly happen and keeping the UAC turned will not affect you however typically this is not the case, MTGO is very unstable and crashes often and turning off UAC is mandatory.

Here is how to disable UAC and get rid of its popups in Windows 10.

Step 1
Firstly, right click on the “Start” button and select Control Panel option.

Step 2
Select "view by: large icons"

Step 3
Select the User Account option.

Step 4
Select the 'Change User Account Control setting' option

Step 5
Select User Account Control settings, and move the slider to the bottom (Never Notify). If the slider is already at the bottom (Never Notify) then move it up, release the mouse, move it down again to Never Notify and release it. Click OK.

Step 6
When you click OK the new dialogue box is open. Click YES.

Step 7
At this point UAC should be disabled. You will need to restart your PC. Once restarted, launch ML Bot using the icon on the Desktop,  if you completed the steps successfully the bot will launch without UAC. If you still see a request dialog from UAC, you did not disable UAC and you need to do again the steps above. If the problem still persists, please contact us via email at staff@mtgolibrary.com or mtgolibrary@gmail.com

MTGO Library Bot 11.36

A couple of hours ago we released ML Bot 11.36, supporting the new set Eldritch Moon (EMN). Prerelease events start tomorrow, Friday.

Please note that previous bot versions are unable to pick Event Tickets while in trade, due to a change with the latest MTGO build (.621). ML Bot 11.36 fixes the issue. We forced the update to 11.36 from the server so you probably already have 11.36 running on your machines.

Happy botting to everyone and happy prerelease events!

ML Bot 11.13 brings Eternal Masters!

We have just released ML Bot 11.13, supporting Eternal Masters (EMA). To trade EMA cards, you have to update the bot client to 11.13 and to download an uptodate pricelist ("CardsMTGO.txt") containing the EMA cards. As usual the pricelist is available for free during the update process and in the bot client installer. LITE bots should update as well.

Enjoy the events and the new set, it is gonna be big!

MTGO Library Bot 11.07 and 11.08

On Thursday we released ML Bot 11.07 and today we just released ML Bot 11.08.

These two updates contains a couple of minor fixes to restore the full bot functionality after Wednesday downtime.

MTGO Library Bot 10.93

The new Magic Online version, released today, requires a ML Bot client update. We have just released the update (ML Bot 10.93) and stopped the launch of the previous versions. If you run an older version you need to update the bot to 10.93. The bot should automatically update, but you can still download the installer from the Online Control Panel.

Please also note that WotC changed the way the "Submit" button behaves. The button does not blink anymore when the buddies submit the trade, and thus there is no way to recognize the submit action. We will try to read the "Trade Submitted" flash message to recognize the action, even if the message fades in few seconds. For now the bot will only recognize the "done" written in the chat, like the old MTGO v3.

Later today or tomorrow we will also release another update, supporting the new set, SOI.

Mtgolibrary Bot 10.73 - Oath of the Gatewatch

We released yesterday ML Bot 10.73, supporting the new set Oath of the Gatewatch (OGW). You can download the updated pricelist from the Online Control Panel or use the pricelist available for free during the update process, or the one in the 10.73 installer.

Lite bots should update as well because the pricelist is necessary to handle the new set.

Please note that the prerelease events will start in few hours, so the prices you find online now are default prices and can be wrong. You may want to adjust them or not handle OGW during the first few hours.

Happy botting and happy drafting!

MTGO Library Bot 10.72

We have just released ML Bot 10.72. Recently we released 10.71 and 10.71.
These versions contains a number of small and big improvements, among them:

• the trading messages are now simplified and allow a smoother checkout process. The order of the messages is slighly different if you have the auto-buyer on or off
• fixed a visualization bug with "Spike Protection". Previous version displayed cards as "spike protected" even if they were not (false positive)
• the autotransfer timer (the "waiting time" between two consecutive autotransfers) has been slightly increased: from 45 seconds to 60 seconds.
• fixed a problem happening on some Win 10 computers blocking the bot at the final confirm window

Installer of version 10.70 was broken. If you want to install ML Bot using the installer, please download the installer 10.72 from the Online Control Panel.

MTGO Library Bot 10.55

Today we released ML Bot 10.54, with the Spike Protection tool http://mtgolibrary.blogspot.it/2015/11/spike-protection-tool.html

There was a crash happening on some LITE bots - we have just fixed it and released the update.

Coming soon: Prices and Margin Tab

In two weeks we will be making some changes to our pricing structure, this will include a format change of the official pricelist CardsMTGO.txt and the addition of a brand new tab to the Bot UI (Prices and Margins tab). You have to do nothing, no action is required from you.

First lets talk about the format change of the CardsMTGO.txt file. We will be removing the buy prices. Example of the current cardsmtgo.txt file.

20678#20679#000#0001#5DN#C#Abuna's Chant#0.008#0.026#0.002#0.008

20878#20879#000#0002#5DN#C#Armed Response#0.008#0.026#0.002#0.008

this is what it will look it will look like when we release the new feature:

20678#20679#000#0001#5DN#C#Abuna's Chant#0.008#0.026

20878#20879#000#0002#5DN#C#Armed Response#0.008#0.026

CardsMTGO.txt will just include non-Foil and Foil selling prices. This is part of the new margin concept we will be explaining in the next section.


New Prices and margins tab introduction:

Currently in the Price adjustment tab you are able to adjust the CardsMTGO.txt files selling prices and buying prices.

This works fine, but there are some problems. For example: what is your profit? Are you now selling your Tarmogoyf for 50 and buying for 35 or selling for 55 and buying for 40? Since there is no way for you to control the official buying price, you simply don't know.

Next week the Price Adjustment tab will retire and will be replaced by an easier to understand tab, named "Prices and Margins". The tool will allow you to define the correction of the selling price over the official sell price contained in CardsMTGO.txt  and the buying price as margin parallel to the selling price in percent.

The buying price will be computed no more as % of the official buying price, but as % of the official selling price. The official buying price will disappear from CardMTGO.txt since it will be no more necessary. As said above, the new CardsMTGO.txt will be like this:

MM2#M#Tarmogoyf#55.160#55.020

and, with -7% and a margin of 10%, you will sell Tarmogoyf at 51.298 and buy it for 46.10 , Having the selling price at 51.298 and the buying at 46.10 means that your margin is 10%.

The migration to the new format will happen automatically: the bot will translate your current settings into the new settings, keeping your prices unaltered, exactly as they are now.

Beta testing results and ML Bot v4 Open Beta

Hello Botters,

with the spotlight over and the chaotic Beta client at rest for now, we can go back to our normal bot business. We had a few ML bots running and we strenuously tested them over the last 48 hours and overall we are pretty happy with the functionality of the bot.

This is post is to present you what we found about MTGO v4 and ML Bot v4 and where we are headed. For those who don't know, v4 will be released on July (here: http://community.wizards.com/content/blog/4083351 ).


First of all, the bot and surprisingly the beta client were very stable and we reported no unexpected crashes, there were a few minor issues and speed needs to improve, but these are easy fixes. This was our first serious test with v4 and we are happy to say that ML was excellent - we could even release it today and everyone will have a stable and efficient bot. ML Bot for v4 has the same functionalities of v3, with a very similar user interface. You will get used in no time.

Our goal for the next 2 months is to further develop the bot and have an updated, easy to use and fully functional v4 bot by July 1, 2014, this is when we will start open beta testing. The Beta client will go live on Mtgo mid July, not only will we be ready but we will have the best bot, with the best feature to the open public that follows the guidelines of WOTC.

Get excited, new great things are coming to ML Bot soon.

Happy Botting,
Jason - Teamstoge
