CDJ 3000 Not Recording

So I'm trying to record on rekordbox 5.8 but its the first time I'm trying with the djm900nxs2 dj link and cdj 3000. I used to record my sets with a ddjrz controller but no sound shows on the master out recording equalizer at the moment. I recorded an hour but no waveform showed up once analyzed, it was just a white line.I did download the djm900nxs2 driver thinking it would work. Cdjs are updated to latest firmware. Also don't know how to unlock recordbox 6 with cdjs so i don't know if i need to purchase a plan because i just play off of usbs.  i just want to simply record my sets.
