Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, yesterday I tried to login and it didnt get any connection then I tried again and it said my account was banned. I tried writing other account name and password and still said account banned. I waited like an hour and tried again and it worked.

But today when I try to play.. same thing. But now It doest go away. I have installed a fresh client from the homepage and realmlists are correct etc.. I dont know what to do.

Character name is Domedagen.

Thanks in advance.
