I keep getting bumped back to login after getting to server select and hit play

[Rubyt]

I can get to character select I do that and the music starts but the loading thingy never shows up and all of a sudden I'm back at login. Then I can't get on because my char isn't logged off yet. It happened last night on a different computer... not sure if it's happening to anyone else. Also could it be a timed out thing...I do have dialup so it's slow but haven't had a problem til last night.
I did try to look for other posts but it came back with nothing.
