Client file corruption detected, closing game client.

Hi mpgh,

I have a brand new hp probook 4540s laptop I just got running windows 8, and I've been installing all my fps and rpgs onto it. ive ran diablo 3 and wow and the graphics are really great on it. I installed crossfire, but every time I try to run it, it gives me the stupid error "client file corruption detected, closing game client.". I've seriously tried almost everything to fix this error. I've reinstalled it, downloaded and reinstalled it, installed it in safe mode, ran it from the direct file, the only thing I haven't tried is running it without an antivirus, but I don't think this laptop came with an antivirus. im running out of options here . Pleaseee help!!
