pretty much decided that it will not run on my good computer. It disabled Mcafee and still nothing, so I uninstalled it. Tried CA security because it runs on my laptop with that on it and still won't work. Tried with nothing and it still doesn't work. This game honestly hates my computer because everything else place on it. I am going to upgrade to Windows 7 anyways when it comes out so hope that works, playing on the laptop is a little difficult.
