How do you start the game after it is downloaded

One way to play a game once it is downloaded is to go to the games screen and it might be there (Vista). You can also press the save as button before you download and choose an area to save all of your games that way you can find them later. Otherwise, the computer will select a spot that you usually don't use to download to and you'll never be able to find them. Lastly, you can search one word of the title to see you can find the game if you already downloaded it and can't find it.
