CDJ 2000NX2 and Licensing

HI

I was in Pirate Studios using their  DJM-900 NXS2 and 2 CDJ's 2000 NXS2.  I connected my laptop and when i try to select and press the rotary buttons on the CDJ'S the rekordbox symbol does not appear and therefore i cannot choose a CDJ ("choose rekordbox dj deck") does not pop up. does this mean i have to subscribe the at least rekordbox core plan? 

Am I also right in thinking that CDJ-3000's would not require a plan?

Thanks John
