I am test driiving Zencart and have version 1.3.9d

There are things that worked a few hours ago, but do not work now. I am trying to set up a free download. I have created the product, Option name, Value name. But when I fill in the Attributes menu and click on "Insert", nothing is recorded...this says "No Attibutes Defined" This is the reason, I assume that the download is not working as I cannot tell it the filename. While the store is run, instead of a download, it asks for shipping info.
