You are already connected to the server.

Describe the problem. Be as specific as possible!:
Sometimes when I log into maplestory, it doesn't load the channel that I want to connect to. After a couple minutes I get disconnected from the game. When I try to log back in, a window comes up saying either: "You are already connected to the server." or "This ID is already logged in or the server is under inspection."

Its been nearly a day now since I've become locked out of three accounts. I've tried rebooting my computer, using a different computer, using a different ISP, I can log into other accounts. I've sent a ticket to Nexon, but my friends say I can't do anything besides wait for the next server maintainence.

Did you use another account to see if someone's already logged into your character?

this happened to me, after about 48 hours i was able to log back in. i did submit a ticket, but it is still open of course....

Apparently when I disconnected at the login server, nexon's server didn't recognize the disconnection although my client did. So until the next server check or maintainence I am locked out of my accounts.

Same problem, but my account gets disconnected after like 10 minutes. Whenever I get that message, my character that I played as last, logs back in, according to a real life friend.
