Im havingtrouble trying to play

[Cerberus762 10]

When I first installed the game I kept getting an error message telling me my CD key was wrong. After about 8 tries it just installed. I can play the game but for some reason when I try look around my character seem as though hes drunk. It is almost as if there is severe lag even on the lowest quality visual settings. My computers specs are above that of the minimal required to run the game. The last problem im having is whenever I try to install the update it gets to 100% then it gives me the Wrong CD key even though It never asked me to enter one. Im very eager to get this game working, someone please help me.

Disable post processing (video settings), make sure your 3d resolution is the same as your resolution, and contact the place you bought it from because it sounds like they've given you a pirated cdkey

ArmA II uses antipiracy software called FADE, which causes the game to become unplayable (i.e. game looks like the player is on drugs, can't aim, etc...). So if your copy of ArmA II is not legit, FADE will kick in and cause your player to appear drunk.
