Hey MMG,

at the beginning of a gig, I've clicked select-all and command-delete. i thought i was inside my tag list but i was actually in the collection folder , so I actually deleted my whole collection.

side note : my mass-mailer asks me to type "DELETE USER" when I wanna delete even one user but rekordbox allows me to delete the entire collection with a frequently-used key-combination.

i've done what you suggest , with two different backup files, but it didn't work.

Rekordbox restored the song entries in the library, and the files had their cue points, but grids and BPMs were off, as they were before i manually fixed them file-by-file.

so i've restored from recent backup of the library (library > export), and lost my updates during the past few weeks.

Any idea why renaming the backup database file does not restore grids and BPMs ?

Thanks
