Unity 4.6 or 5 Dk1 Tuscany Demo (new to unity)

I am attempting to get the Tuscany Demo working on a DK1 using unity 5 (will attempt unity 4.6 next). I am trying to understand assets vs projects vs unity packages. here is what I think I have learned. unity packages are packages that contain all files for a project and can be double clicked to add these files to new/currently opened project. Once they are added, you can choose the scene to display from the project and run this on the oculus. This doesn't work for me. All I see is a horizon like view when I run the Tuscany demo. Any help or suggestions would be greatly appreciated.
