WotLK Log-in issues

[Jordanofwarz]

I downloaded the WOTLK client last night from the website and tried to play it an hour ago. I had check to make sure the realmlist.wtf file was correct as I always do and this is the error I have gotten every time I have tried to login with my account name and password.

Has anyone else experienced this problem, I'm confused because the servers appear to be up and although I realize the BC server is being released today I doubt that could cause this problem.
I would really appreciate some help because I'm clueless on what could have caused this :/

Edit: The problem seemed to have fixed itself by me moving around the folder. So if anyone has any similar problems trying to connect moving their folder to other locations as it may help :)
