I really have a lot of fun with this program, but with respect I have to insist that the problem lies on the server side. This morning I was logged in just fine. I logged out and left for a few hours and came back, tried to log in, and since then...no luck. Nothing at all was changed on my system hardware or software-wise.
Might I suggest that you might reboot your end?
Thanks - keep up the good work - this thing is bound to grow.
