Rekordbox 5.0 crashed several times during live performance

Yesterday I had a 5 hour gig in a club. My setup was late 2013 MacBook Pro (fully upgraded OS etc.) Running rekordbox 5.0.0, 2 CDJ's 2000 Nexus and, 1 CDJ 2000. As a backup I had the CDJ 2000 not connected to rekordbox and I was using flashdrive for that CDJ, which I also linked to 1 CDJ 2000 nexus with lan cable.

2 CDJ'2 2000 nexus where connected using USB to MacBook. During my performance rekordbox crashed several times by not loading any track into a player, the screen just freezed on the Mac. As a result the player I was trying to load the track into it, also stalled. I had to quit rekordbox and CDJ 2000 nexus player to get all booted up again.

This happened several times during the performance. I'm so glad I've used one player with flashdrive for being the backup plan, otherwise it would have been a failuere of a kind that no DJ wants to have in a packed club.

So for those out there using rekordbox 5 in a live setting, make sure you have a backup plan at hand so your show does not get **** up.
