BPM JUMPING UP AND DOWN AND LOADS after 15-30 seconds / playlist export

Hi Guys,

I have a question i upgraded to rekordbox 4 on my osx el capitan.

I have an i5 processor with a 1TB SSD and 16GB RAM.

I played lately on the cdj 2000 and the nexus and the xdj100.

With all i have the same issue, the bpm is not loading before i press play, before upgrading it ways always working perfectly.

Also when there is a break in a track the bpm jumps down between 0,3 - 0,5 BPM. (this was also not happening before.)

I want to have it as before with one steady BPM when playing and that the BPM is loaded when i select a track before i press play.

Last but not least when i export an playlist the cdj shows me [folder] --> [content] [artist names folders] sequential, but no playlist.

If there is any further information required don't hesitate to ask.

If someone can help me out i would highly appreciate it.

Best Regards
