Need Help!

Okay, so I recently loaded CrossFire at a different house at which I am staying over for a couple of weeks, and when I open it, it says something like this "Client file corrupted, Closing game client" an it just closes. My apologize if this has already been posted, I can not find it anywhere. Can anyone help me solve this issue please?

Operating system: Windows 7

PS: I have already tried re-installing it, so that doesn't work.
