Server Bug
 

Cant get on this just keeps poping up on the login screen please help

Read the front page news. The main server is currently closed to facilitate Velious beta testing. When you log it it's copying your characters to the Velious server then logging you out.

Unless you're trying to log in to the beta server, I can't tell from the small screenshot.

You can easily tell.

He has a server from the green list highlighted (P1999Beta).

Does someone else have access to your account? Beta allows boxing so people box characters a bit for buffs and to fill out groups.
