CAN ANYONE HELP ME PLEASE?

I'VE DOWNLOADED WOTLK AND WHEN I GO ON WOW IT COMES UP WITH
The file "C:\Documents and Settings\All Users\Documents\World of Warcraft\World of Warcraft\..\Data\interface.MPQ" could not be opened. If this problem persists, you may be able to solve it by uninstalling and then reinstalling the game. If you are unable to correct this problem, please contact Blizzard Technical Support.

WHAT SHOULD I DO? PLEASE I NEED HELP OR I CAN'T GET ON WOW TO PLAY :S

One of the things u could try is to uninstall WOTLK and do a repair on the game couse it must think that the interface is damaged so if u do a repair then it may solve your problem. That is what i would do to begin with

i'm trying to reinstall it but it keeps coming up with a error messege at 50-60%



Downloading wotlk has made everything crapped up

It could be that your computer is behind a firewall and seeing the download as a threat so try to switch off the firewall or make a hole for the download to come through or go and buy the game CD it has no troubles loading on my laptop and it took like 5-10 mins
