I had the v.2.1.36. I tried to import from my Serato playlist a large bunch of track (40k) as I updated my track infos .
When I opened the software and drag to rekordbox playlist or Rekord Buddy playlist it crashed.
I tried several time with same issues until the point I could not launch it anymore.
I looked this forum and have seen there was an update (v.2.1.40) so I downloaded it.
I still have an issue, I even can’t launch the software, it still stuck to the launch page at “Readying the FLAC jacket”
