When I start the game, I get a black screen. No error message, no music. I alt-tab and can see the icon on my desktop. Task manager shows it's running. I alt-tab to the game a few times and it finally goes to one of the starting movies, plays then goes back to the black screen. I have to keep alt-tabbing, trying task manager to select it, before the game starts. When it does, it plays fine.
