Hi i just loged and played at friend's home who playing on nostalrius too, maybe you'll think i use 2 account's but it's not. My name's character is Shaktã and i played on the pvp server. Please deban my account.
The account associated with character Shaktã on the PVP server has never been banned. Your hunter and warrior are both safe.
Probably you typed in the wrong password too many times either on your account, or your friend did on his account, resulting in a temporary IP lockout. You can wait some time (30 mins to an hour) and try again with the right password. If you cannot log in, you can always change the password by going to https://en.nostalrius.org/password.
