Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi i recently started playing and i made my toon and when i logged off my toon and looked at the other realms and clicked on a test realm and it keeps dcing me! Any time i go to log it it just says dissconnected. Ive tried the whole doing what the beginners guide has said but it's not working. Please help

throw away the wtf folder in your wow folder and then restart wow. That's a good place to start...if that doesn't work use the search field above to find a gazillion solutions to your problem.
