DVDFab HD Decrypter 13.0.6.6

I have been using the free HD Decrypter for some time now. It works great and updates for new movies come out frequently. However, once you use any of the trialware, access to the free HD Decrypter goes away.

I bought the Ripper and now when I try to use HD Decrypter I get the DVD Copy instead which expires after 30 days.

An uninstall / reinstall seems to reactivate the trialware but it would be better if the HD Decryter access was not disabled when you purchase a license to some of the features of the program.

By the way Ripper is also a great program for converting DVDs to avi or other formats.

So far I like this software. But I have one questions here.

Where is the difference between DVDFab HD Decrypter and the DVD decrypter for decrpyting DVD. DVD decrypter was banned awhile ago by the movie industry. But why DVDFab HD decrypter is legal?
