Ok, so I tried downloading Feralistic 3, but then it messed up the game with the 'exception' error coming on all the time, so then I uninstalled it, but when I try reinstalling it, whenever I start FHSetup, it brings up 'User Account Control' asking if I want to really run it, I click yes, but the screen freezes, and when it finally unfreezes, the setup doesn't do anything. What do I do?
