Hi, this problem usually occurs as a result of being disconnected, or closing the game without logging out. Your account is deadlocked in the server and will be until a server reboot occurs, which usually happens as a result of a server crash or maintenance.
I have successfully logged into the account on a different server, so your explanation is most likely correct, but it could be several days until the next reboot. This is very depressing.
Try restarting your client Toasty ^_^
