Well, the "Service Overloaded" error just means that the server has had a lot of people logging in at the same time as you.
Try waiting 10 minutes, if this doesn't work .. i saw hampa saying something about logging in on server 1 or 8.
So try going into the first server on the list and typing in /Login Poplop Password
(password with your own, of course)
What operation system are you on ?
also, do you have Toribash 3.04?
