How to open 2D tutorial project?

I just started using Unity and for about two weeks now have been trying to learn as much about scripting as possible before attempting to create a game. I downloaded the project file for the 2D tutorial Unity created found here. After downloading and importing the files into Unity I have all the components such as scripts and animations but nothing appears in the scene or game windows. All I'm trying to accomplish is to see and test Unity's game to get a better understanding of the program. Any ideas why no scene is appearing?
