Please help!

Hi, when i click "start game", everything does what it suppose to do. Then when the black screen pops up before the crossfire loading page happens, a error pops up saying, "Client file corruption detected, closing game client". I don't have any hacks (nor will I ever) and since i used fraps this happened! But, I deleted everything that had to do with fraps. So, i was wondering if it's just me or everyone is having the same problem? And, I also have hypercam 2. Does that have to do with it? PLEASE HELP!


Thank you for your time,
Sean W.
