Client File Corruption

Everytime when I load up CrossFire, I get a black screen saying "Client File Corruption, Closing game client." and it disconnects me from the game. I have redownloaded it 3 times and I get the same error. I have uninstalled and reinstalled, but get the same thing. I have even reset my computer and IP, but still get the same error. Anyone else having this problem or know a fix for it?

Please and thank you.
