I found a work around. Logged into my account at DVDFab, went to the Download Center and downloaded DVDFab Toolkit from there. I then installed using that download (where the installer really works!) and used the Key from SOS to activate. (I think I had to use ctrl+v vs paste.) Anyway, it worked and now shows an expiration date of 21/09/23 (Sep 21, 2023). Hopefully this will work for others that were having problems.
