Nostalrius Begins - Quality wow vanilla realm (1.12)

A moment after walking into bfd i got dced and I can't log in since then.. It doesn't even matter what password I type in, every time I get unable to connect message after a really fast authenticating and handshaking. If I try some random account name then i get a proper error though... Does anyone know what's up? I tried using login2 realmlist already.

My account name is Aisu2
