I didn't reinstall Windows, however I also get the error message "Unsuitable game client version detected. This modpack is made for WoT 1.9.0.1 only!" when trying to install version 1.9.0.1_08. I had no issues with version 1.9.0.1_01. Game is up to date and runs fine in Vanilla, but I don't want plain Jane as they say. Missing the things I like with the Mod.
I have attached the WoT_log, but not sure if it will help with the most current version as I haven't updated since version 1.9.0.1_01.
