I manage to log in after the server reset. But not long afterwards the lag made me die while training and when I press ok to respawn, my screen just froze up. Now i am unable to log in my account anymore.
in case you are talking about character stuck, when u tried to log-in you encounter "your account has been logged on", you may use another account in game to @unstuck, input your character ign, input your account id and password (cant remember which, or both).
