I just purchased a brand new Dell laptop with Vista, and whenever I try to create a new family, it will freeze.
It will also freeze/stop loading when
-I try and load some households
-I go downtown
And sometimes, I will completely load a household, but the screen (minus the control panel) will be black, and the music will be playing, but nothing will show up.
I have already uninstalled and reinstalled many times, and this still happens.
I played these games on my old computer and this never happened.
Help!!!
