I just had windows 7 64 bit installed on my computer. I am not at all familiar with win 7. I have installed the enhanced client and when I go to start the game, it asks me if I want to allow this program to make changes to my computer and I say yes. Then I get a rotating circle thing at my curser for a short bit and then it disappears. Before I I go any further, is there a compatibility issue with running UO on a 64 bit computer? If not, whats going on?
