You are "Ghosted" on the server. Basically, the server did not record that you logged off when you did, so it still considers you to be on. Try rebooting your modem at the same time you are rebooting your machine. Sometimes, the loss of your connection to your ISP will let the server know you are no longer connected. If that doesn't work, your best bet is to contact Frey, and ask him to reboot the server because you are ghosted. When the server kit reboots, you will be automatically kicked off.
