Can't get past "registering agent" AGAIN....

I know this glitch will probably kill itself off in an hour or so, but what the hell, here goes.

I got ingame on my first try tonight, immediately decided to teleport to my home, but got stuck on the "contacting remote server" bar, so I had to close the game and login again. I do the same thing, the bar gets stuck again, I close the game.
From then on, whenever I tried to log in, I got stuck on "registering agent" while loading. 5 times in a row it happened, then i rebooted, did it another 7 times, got new video drivers (yay they came out yesterday!), rebooted, and just tried a few more times to log in.

I've been playing with preferences, re-typing my name and pass, to no avail. Oh Lindens, what ever shall I do =(

I am having the same problem as Dave and it all started with teleportation... *cry*
