This is meant as a guide to help you locate and resolve the most common issues running MTG Arena Tool. Please only follow these steps if you encounter one of the issues mentioned.
This is probably caused by an error reading the user configuration, probably due to an unhandled exception or new data added from MTGA that mtgatool is not handling properly. Bear in mind this issue is not because of a bad or improper installation, so reinstalling will make no difference. Altrough, you can roll back to a previous version safely if an update caused it.
Locate your log and config files;
- Close MTG Arena and MTG Arena Tool.
- Go to
%APPDATA%\..\LocalLow\Wizards Of The Coast\MTGA\ - Proceed deleting
output.log. - Run MTG Arena, once open, run MTG Arena Tool again.
If that does not work;
- Proceed to
%APPDATA%\mtg-arena-tool - Locate a .json file named with your User ID, something like
0A1F2E3E4D5C6B7A.json - Rename the file, adding something to the end. Do not delete it!
- Run MTG Arena Tool again.
If the last step worked, send the the .json file to [email protected] and I will inspect what is wrong with it.
