WotLK Bug in log in

[Sevy]

Good evening,
Well last night I logged out normally, today when I tried logging in I got a pop-up just after Authentification saying my account has been banned.
A friend tried to log from her pc and it worked perfectly, I don't know what is the problem.
Thanks in advance

Does it mention any ban?
