Need help with connection problem (Private servers)

[tobbelainen]

Hey, ive looked all over the web the last couple of days but i havent been able to find a good anwser, hope this post isnt in the wrong forum section, if it is, just remove it. Anyhow, my problem is this that everytime i get connected to a private server it loggs in, then says "Your account is authorized for WOTLK but the computer your playing on does not contain WOTLK data."

Im running the retail enGB version of the game, patch 3.0.3. Anyone have a tip for me how to solve this problem? +Rep if any help is given

You did say you have WotLK already installed correct? Try deleting the Cache? or downgrade patches. One of those two may work.
