Hi, I'm having problems running my Galactic Civilizations II. It installed properly, but I can't get the start screen to come up. The first time I tried it after it was installed, it worked well, but after I put in the information about what civilization and the size of the galaxy I wanted it went blank. The screen wouldn't come up after that. I tried uninstalling it and then reinstalling it, but it still didn't work. It just stayed blank every time i tried playing it.
