reading problem older files

[riens12890201]

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?

Parts of you question are hard to understand.  What do you mean by "replace the backup"?  Have you moved or deleted the original media?
