For anyone else in the future, I had the same issue to where Psinet was literally crashing Stormfront. I'd barely get into the game before it'd kick me right back out... I just went to Add/Remove Programs, deleted PsiNet, and was good to go. If you don't do ANYTHING else with the program before that, I don't see why it wouldn't work. If not, you're going to have to uninstall pretty much everything to do with GemStone before reinstalling.
