I've had to wipe out my hard-drive, reinstall Windows, and have created a new profile (many thanks to the Microsoft tech who has helped me with ALL of this). When I open MusicBee, it finds my music files, but all my custom sorts are gone (last name, first). I have a Carbonite backup, and if I knew where to look, I'm hoping I can find the file with my sorting preferences.
Many thanks!!
