Laptop crashed but I recovered the files

My laptop crashed but I was able to take it to a repair shop where they pulled all my files from my old laptop.  I downloaded rekordbox on my new laptop and copied the files over but I can't see my old music, or my playlists.  I tried my best to copy the locations of the files the same on my new laptop.  What am I doing wrong?  I tried to look for a solution but the one I found had a link that gave me a 404 error.  Please help.
