Nostalrius Begins - Quality wow vanilla realm (1.12)

So the sever was down and I was looking at the realm list and accidentally clicked into the test realm and the game disconnected me. Then I tried to log in to change the server but I keep getting disconnected.

I got that exact same problem, i wanted to reconnect to the nostalrius begins, but clicked test by mistake
now i am kind of locked to that realm and keep getting dc'ed.

How can i change back the realm?

Read those stickies up there that offer suggestions or say read me before you post. Or search for any of the 9000 similar threads...anything but making another thread on the topic.

I wish I had five bucks every time this thread was made.
