Nostalrius Begins - Quality wow vanilla realm (1.12)

So I accidently clicked the test realm 2 when logging in, and now I cant get back to the normal realm. It wont bring up a realm list, just disconnects as im trying to get to the login screen. Any help on getting this fixed?

I recall there is a "Change Realm" thingy up to your character list.

well that's the problem, im stuck at the login screen and it wont let me get to my character list. everytime I try to get to my character list it disconnects me

Open WTF/Config.wtf
Look for

SET realmName "Test Realm Name"

Replace with

SET realmName "Nostalrius Begins"

Play!

sweet, thank you!
