MapleStory crashing?

I can't play, I either get disconnected with a "your account is already logged on" Or, MapleStory crashes with an error "Disconnected from server".

That's all there is to it, I can't play, Period. Anyone know how to fix this? (My internet is fine and I already re-installed).

Same thing happening to me. It's really annoying since I cannot create a new character for pirate. arh

I've heard this is a Vista related glitch, are you using Vista?

Windows XP SP2....
