you said that the servers are up and running. but i see you are still under maintenance. how about fixing this "play" button. 30 mins after you said that the servers are running and still can't log. (not only myself, many ppl have the same problem.)
i managed to log after restarting my pc. (dont know if restarting actualy did anything) then got disconnected and its on tech maintenance. update: seems to be on now.
