Juellz,
Do a full uninstall and reinstall of the game as well. After uninstalling Wow, clear out your temp folders
C:\Windows\Temp
C:\Documents and Settings\<YourName>\Local Settings\Temp
(Delete all files in these folders that you are able to. Some files may be used by other programs and not able to be deleted.)
Also, delete the following folders if they exist:
C:\Program Files\Common Files\Blizzard Entertainment
C:\Users\Public\Public Documents\Blizzard Entertainment\World of Warcraft\
Then reinstall Wow.
