Dunno if this works or not..but you can try

1. Open your World of Warcraft directory (This is commonly located at C:\Program files\World of Warcraft)
2. Open the folder called "Data"
3. Delete the Patch.MPQ file
4. Run the repair.exe utility found in the World of Warcraft directory
5. Click the button "Reset and Check Files"
6. The repair utility will say, "World of Warcraft is seriously damaged and will need to be reverted to an earlier version. After it has been reverted you may need to patch up to continue playing."
7. Once the repair utility has completed, you will need to reapply the patch to enter the game. If you are having problems with the patch actually updating the game, this is most commonly corrected by uninstalling the game, then reinstalling, and trying the patch procedure again with no other programs running.
