I can't launch the game from Steam. I click on "Play", and steam announces that the game is running. The Stardock launcher appears, offering me a choice of games to launch. I click on Galactic Civilizations 3, then click on play. The launcher disappears, and steam confirms that the game is running - for approximately 1.5 seconds. Then steam reports that the game is "syncing", and then it is ready to play. At no time does the game actually launch.
