Thank you, but I figured it out on my own. For anyone else who may me dealing with this same scenario, here's what I did. First, I used my favorite uninstall program to delete both DVDFab 12 and the mini version. Then I did the same thing with DVDFab Player. Then, I searched for any leftover remnants of the DVDFab software including the log files (which the uninstaller didn't delete). After that, I re-downloaded the latest version of DVDFab and it runs as it did prior to installing macos 12.2.1. Hope this helps someone else. Peace, Jim
