I recently modifid the ini file( I think it's thirdechilon) well now I can't start the single player campaingn!!! Whenever I start the new game where you are trying to pick the lock; I can't pick the lock and my screen is all white excpet for the tutorial box. So.... am I screwed?

Simpley find the original .ini and replace it. If that is all that you have modifed then it should return to normal.

ok, fine I thought that was the only option
