"this account is logged in"?

i was just in the game, and all of a sudden got disconnected. when i tried to log back in, the game client told me my account is already logged in.

is it possible that i've been **** already? i just started playing yesterday.

edit- ok, it's getting weirder now! i managed to get into character select screen, and my character is swaying super fast! i manage to get in game for a minute, it tell's me "disconnected from server," and all the mobs are racing around super fast! lol

what's going on?
