Could not load config

Can someone say what i should do?
-I do everything like uninstall and install

Hey @masiuk, we're looking into this issue. Send us a message to with your DxDiag.txt and Log.txt, if you have one. Latter can be found in C:\Users*username*\AppData\Roaming\MudRunner, but it may not be there.
Additionaly you can try creating empty Config.xml file and put it to C:\Users*username*\AppData\Roaming\MudRunner to see if that helps.
