The software works best in tandem with the book which may be hard to get now if you haven’t already bought it. The new version install readme file hints at a new vendor for Willmann-Bell publications so perhaps business will continue again soon.

I have the book and older registered version of the software which I had to uninstall before I could install the newer non-registered and updated version of the software. If you are a beginner you will find it difficult without the book.
