This is the first time I've experienced this. I have Windows XP Home Edition and I normally use my admin account to get on the game. Lately I get to the login and I type a few letters and poof the game closes. So i changed some video settings and it allowed me to get on again. The next day it started doing the same thing. I changed the settings back and still no good. So I figured I'd get on my wifes admin account and try it there. It allowed me to get on the game and I tried to go to the powerup store, as soon as I clicked on an item the game closes again. Any help would be appreciated.
