CALL OF DUTY
Thanks for taking the time to post!
I am sorry to hear about the game crashing on you. If you have not yet done so, please try to completely delete the game files, and then reinstal them.
Can you let me know what graphics card you are running and make sure that you have the most up to date drives installed. If you run your DxDiag, and click on "display 1" check the drivers tab and let me know the date that is listed.
