Is Bootcamp Demo Still Usable?

Hello. I found a helpful-looking tutorial ( http://code.tutsplus.com/articles/getting-started-with-unity--active-8031 ) based on the Bootcamp demo, but got a series of errors when trying to load the resources and follow along. First of all, should I give up on trying that set of resources in favor of the Robot Lab material? If not, how can I get it working? Am I making some basic mistake in how I import resources?

Specifically, when I tried downloading and importing the assets from the Asset Store, I got: "Moving file failed Moving C:/Users/owner/Documents/Unity/Temp/tempFile1 to C:/Users/owner/Documents/Unity/Temp/tempFile" Followed by: "Moving file failed Moving C:/Users/owner/Documents/Unity/Temp/tempFile to C:/Users/owner/Documents/Unity/library/metadata/be/[long hex string] failed: Access is denied."

And then I wasn't able to open the project up, presumably because it never installed properly. So... Best to focus on the Robot Lab tutorials then?
