Client File Corruption Detected

Since the few posts I've seen about this error have been completely useless and utterly without intelligence I figured I'd at least make a post that's slightly more useful.

Just went back to Windows XP SP3 from Windows 7 and installed the v1045 client that I had backed up for reinstalling my OS. Everything went like normal until I tried to run the game. Went through HGWC loading went without a hitch but once it got past that I got this error.


Thought to myself that the v1045 might have gotten corrupted somehow so I downloaded the latest client (v1051) and reinstalled Crossfire once again. Unfortunately it gave me the same problem. I'll try downloading and reinstalling once again but something tells me that this is just more z8 fail.... get your **** together will you?
