Alright, so I have recently downloaded Steam For those who don't know about it, and are reading this for some reason, is a software that has PC Games that can be purchased without running out to the store for a CD. When I downloaded Steam, I first decided to download Team Fortress 2. When I tried to play it, it loaded, then it showed the Valve Logo and such, then it went back to my Desktop, meaning it automatically crashed or something. No, it did not give me an error message. So I decided to try a different game. I randomly downloaded the demo for the game Cloning Clyde, which I only played once on Xbox, and when I tried starting it up, it showed the Window Box that the game is displayed on for 1 second and it disappeared without giving me an error message. What's happening?
