reading problem older files

Had a crash with a laptop with premiere elements 18 (2020). Good backup of all adobe files.
Bought a new laptop, installed a trial version of 2022 and replaced the backup.
Starting an exinsting project cannot find the media, although all are available in the copied backup files.
All are there: .prl. prev. etc.
How do I recontact the foto's, video's and music?
