I had version 1.03 of Rebellion previously, and I never had any problems.  However, after Steam automatically updated me to v 1.04 of Rebellion, I have not been able to play a single player game.  Whenever I click on Single Player, the game just crashes back to the desktop without giving me an error message.  I have verified my files, so that isn't the problem.  I even uninstalled the game and redownloaded the game and installed it.  I am able to play multiplayer, but I am not able to even click on the Single Player icon without the game crashing.  Any ideas?
