I ran my program and it gave me the following error:

ERROR #121 (0x85100079) Version Mismatch
Program: C:\Program Files\World of Warcraft\WoW.exe

DBFilesClient\Spell.dbc has wrong number of columns (found 232, expected 239)

I ran the repair and nothing wrong came up. What should I do?

Hello Bortdort

Reverting the game to a previous version may also assist with the troubleshooting process. In order to revert the game to a previous version, please try the following steps:

1. Open your World of Warcraft directory (This is commonly located at C:\Program Files\World of Warcraft or C:\Users\Public\Games\World of Warcraft for Vista users)
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.
