Please help me with this error!!!

[Stealysteve]

Everytime I go to play a mission, training event, or what ever it may be, towards the end of the loading bar (around 80%) an error will pop up and say "An external component has thrown an exception." And it will kick me out of the loading screen and back to the menu. When I try to do it again It'll keep kicking me out until the game crashes. Please help! I mean I when I pay $50 for a game I expect to atleast be able to play the God damn thing... Any help would be greatly appreciated! Thanks for your time
