Critical Error #131

[Drbuttstuff]

So during a flight from Orgrimmar to Azshara somewhere over the coast of Azshara, I encountered a WowError that causes the game to crash. Every time I try to log back into this character, the game crashes instantly with the same error. Any suggestions?

The WowError information is below
"This application has encountered a critical error:

ERROR #131 (0x85100083) File Corrupt
Program: <WoW file folder installation location>
File: Data/patch.MPQ

I'll suggest to first try delete your WDB folder and try, if the issue persists then remove the patch.mpq file and get a new one from your game backup. If you dont have a backup, then repeat an installation process. Seems that the major files of the game got corrupted for some weird reason.
