Ever since I tried to minimize the game to stop my music it now won't start the splash screens goes the windows opens then immediatly closes, I have got the hotfix 1.03 but when it opens it saya the serial cannot be found then closes. I got the game through steam. So what's ocourring?
Usually steam will have any updates for the game. Steam games are not located in program files, but INSIDE the steam folder in program files.
Have you tried forcing a different resolution: Right click on the game in Steam - Properties - Set Launch Options. Then type -RenderProfile_ResolutionX 1920 -RenderProfile_ResolutionY 1200 Replacing the 1920 and 1200 with a respective resolution - try a lower one and see if you can get in.
