Restoring playlists using backup files

Hi, I created a long playlist in a 2021 version of DJ Pro. My iMac hard drive then broke. I bought a new iMac and downloaded DJ Pro AI. I have the backup files from 2021 and all the music files (that have not yet been imported them into DJ Pro AI). When I open the backup file nothing happens. The DJ Pro manual doesn’t talk about backups. My question: Is there a way to use the backup files to recreate my original playlist, and what are the steps for doing this? Thx in advance.
