Engine 4.2 won’t sync the database structure, only all music files

I’ve updated to version 4.2 on my pc and on my prime 4 I’m a windows user When syncing my library all my music files get synced, but without any structure. So I can’t access my maps just all songs.

I’ve tried almost everything. I uninstalled, deleted the backup file, deleted al register keys, deleted my whole database and songs on my prime 4, but still it’s the same result…. So now I’ve to play from my usb witch has de database on it and I can’t play out of my internal HD from my prime 4.

Same issue when trying to sync to a separate empty USB.

When exporting I’ve got to press export to drive twice. First time it’s instantly done, but nothing happens. Second time I see the progress bar and it exports and the I get the results as written above.

Anyone knows what’s going on? Many thanks!

Edit: In addition when I try to copy paste files into the engine database it analyses new tracks, but they don’t show up. Also I can’t remove the folder.

Same problem here. Prime 4+ and macOS 15
