X1 won't connect to my Reckordbox 6

Had Reckordbox 6 with a Pioneer mixer I bought but ? Can't connect my Traktor X1 MK3 to it, how do I do so ? To my mind I have to upgrade to a paid version of Reckordbox ? I am very heavily disabled and need my X1 desperately.

Thanks so much for your help Pioneer,

Martin
