UO Second Age

Whenever i try to log into my primary account the client vanishes! I manage to get all the way to the charactor selection, but when the charactor logs in the client just dissapears. The really weird thing is that i can still hear all the sounds from the game, and can (according to my friend who was logged in) interact with the game, just can't see anything. The really weird thing is that i can log into my second account normally!
I'm running on windows 7.
Any ideas?
Thanks

Right click on the UO program bar at the bottom, and click "Maximize"

This happens to me, what I do is r-click the bar in taskbar and click move. Then press any arrow key and poof, back in the frame it comes.

alt+enter twice works as well

basically just need to full screen the client, then window-ize it again
