I will try to explain the issue: For some unknow reason either ModSettingsAPI or TankCarousel mod are bugging the original WoT files, as long as you use those mods, your game might work fine (although unstable) but if you try to remove them, you will be not able to run the game at all. Solution is to reinstall the game totaly (or copy few files over), but the issue might be back, the way it was there before.
Possible fix in attachment (to fix WoT, not to fix wot + carousel and other fishy mods) Unpack to WoT folder. Note: this is from my EU client, it is unknown how it may affect the other ones. Imho should work fine on all clients.
