Whatever account of mine I try to log in with, I get the error, "Connection failed. If you have just left the game then please wait 30 seconds for your previous character to be disconnected and try again." and can of course not play. I've tried updating the client (and got no new files). I've tried deleting client_default.cfg + client.cfg and updating in case one of those was causing the problem. This also happened when I tried to play a couple days ago. How can I fix this?
