I downloaded the German version and played it online and single player. Now as soon as I launch the game, windows comes up with a message error signature message about a digital signature problem and asks me to Send Error Report or Don't Send. WTF is goin on with this game? Nothing but problems

Have you updated any hardware drivers? What OS are you using? You didnt try to patch the game did you?
