Rekordbox 6 autorelocate error

I have made several playlists in rekordbox with music i have on a USB stick and when i introduced the stick again, rekordbox refuses to read them. The songs are still there but i can't play them, only some of them can be played, the rest have exclamation marks. I have set the auto relocate folder to where the songs belong but it doesn't relocate them, whether i right click on a song or select all the missing files it just says "searching" for 2 seconds and nothing happens. I have restarted my computer, reinstalled rekordbox and the same happens. Is there any way i could save my playlists without relocating them all manually?
