dvs and perormance mode doesnt work correctly for me

I own two cdj 2000nxs2 and technic 1200 mk5 rekordox dvs soundcard and full package of the software I bought a usb 7 ports too.

if I'm in export mode the cdj works fine the (live red Light) comes on the beat bar syncs together fine but I cant get them to work in performance mode but if I do the beat bar at the top doesn't work and the dvs doesn't work either.

once in a blue moon I can connect to rekrdbox performance mode. but the beat bar doesn't work and the live doesn't work either.

is there anyway I can get them to work correctly in performance mode and get the cdjs and vinyl to work together please help me.

Many thanks

Ian
