Database on Windows Laptop crashed. Need help to play back from Prime 4

Hello, my engine DJ database crashed. I made a backup a few days before but can not restore it. The database should not be ok because it has only a size about 1,96 MB (on music folder Drive C). All my music is on another partition D. The database on my Prime 4 (Drive E) has 510 MB. When I connect my Prime 4 I see all my playlists correct, but with directory E of my Prime 4. How can I play them back from Prime 4 to my Engine database on my laptop?? Sync Manager do not work because there is no new data to sync. When I copy the m.db from my Prime 4 directory to my music folder on the laptop all the playlists and track are red because of the wrong directory. How can I change the drive letter? Or how can I play it back to my laptop? PLEASE need HELP… Thank you!!

Nobody knows how to get my Prime 4 database back to Windows Laptop?? Any idea? Don’t know what can I do…
