Just got "Cliffs of Dover". When I launch it, all goes well until I hit "FLY", at which point the game goes away and I'm left looking at my Wallpaper. I can hear the audio, and there's a small, pale blue rectangle in the upper left corner saying "IL-2 Sturmovik, Cliffs...". But that's it. I can see in the bottom tool bar that "Cliffs..." is running. What am I overlooking? And...does this happen to anyone else?
