Disconnecting on Test Realm - IsVV2

[Snezy]

So, I got a little problem here, i found a server called Test Realm - IsVV2, i tried to check it out to see if it was a new server but i got disconnected, now when i try and logg in i just disonnect, i can't change server on the logg in screen so i'm sort of stuck, would be great if i got some help, like a link or something to a guide, or if a game master can change my realm maybe?

Open your WoW folder, locate and open the WTF folder then delete the Config.wtf file.

This will allow you to select the Nostalrius Begins realm.
