I start the game and the screen turns black like it is functioning properly then it comes up with an error message that says, "Crysis Warhead has experienced an error" I have a GTX 560, AMD FX zambozi 4-core, 8 gb of ram, and a 650w corsair PS. Crysis functioned fantastically but this game is being a problem. right now I am stuck with this game and don't know what to do any help would be great thanks

P.S. when I look at the event viewer this is the details
