Mike,
The Extension Library includes all of the WebAssist Extensions, It does not include any of the Solution Packs such as the User Registration Solution Pack. The Solution Packs must be purchased separately.
See the Supper Suite Complete feature List for a full list of what is included in the Extension Library:

You are not missing any files for following the "Introduction to SecurityAssist" tutorial. There is a lot of crosstalk going on in this thread that is confusing the issue, so I will clarify.
The Original suggestion to use the support files in cluded in the Download center is the correct suggestion. however, in the BlueSkyMusic database, there is not a table named Users, instead you should use the Visitors table. This table has all of the columns you will need already set up.
Before starting the Tutorial, run the SecurityAssist wizard to create the pages you will use while following the tutorial. The Tutorial does not come with pre created pages, you must create them yourself using the SecurityAssist wizard.
The Idea of the Tutorial is to teach you how to modify the pages created by the SecurityAssist wizard to utilize password encryption.
