I found out that if you can't connect to a server and just hang, there is a way around it. This happened to me earlier in the week with Luciel; I would login and just sit at the blank screen.
What you do is login and tell it that you -don't- accept the eula. It then boots you out of the game. Reconnect and login and this time accept the eula. You'll be presented with the server select screen. Problem solved.
Now if only I had this earlier in the week when I had a little time. :)
