Not loading past the load screen.

Wayton,

Lets reset the game to default settings to make sure its not just having a hard time loading in game settings or certain addons.

With the game closed please try moving or deleting your WTF, CACHE, and INTERFACE folders out of your World of Warcraft directory. These are temporary cache files that will be recreated by the game the next time you launch. Moving them to the desktop makes it easy to replace them if necessary.

Please also note these folders contain your saved UI addons. If you're using Windows Vista, please remove those folders from the following location as well if it exists:
C:\Users\%username%\AppData\Local\VirtualStore\Program Files\World of Warcraft
