I FIGURED IT OUT!!! I had to redownload and save it to my desktop. After the download, which contains two files--Roxio 2011 and Roxio 2011 Content, I had to go to the folder (under the download file) and open the content file. It's confusing because Roxio2011 runs automatically but the content file doesn't. I had to run it myself.
Thanks for everyone's help. I wish that the Roxio tech support knew more about their product (see excerpt, from my convo with them, above)
