The problem is the server, not your account or anything of the light. The server has been under a lot of pressure with the flux of all the users online lately, what with the addition of the wings. This server issue has been occurring pretty much every night around this time, when the majority of people get on, (at least that is what I read on a similar post.)
The only thing you can do is wait it out. It could last from a mere thirty minutes to over an hour. But once you see the player count at the top of the forum going back up instead of dropping, you'll know the problem is fixed.
