Nostalrius Begins - Quality wow vanilla realm (1.12)

so on one of the server crashes i assume i was kicked to to character screen and couldnt login so i was looking at the realmlist and i clicked on the IsVV2 realm and was instantly disconnected from the game now i can not get back on and have no idea what to do

Hi. You can set the realmlist manually as explained in the stickied post with the apt name "SOLUTIONS FOR CONNECT PROBLEMS, READ BEFORE YOU POST"
An other way is to quickly cancel as soon as you log in. This should allow you to change the realm from within the client without editing any files.
Good luck!
