Rokordbox software

Hello 

This is my 4th DDJ controller. But everytime I'd like to activate the Rekordbox software, I have to pay a great amount.

My last Controller is FLX10 I bought since june 2024. How come, I cannot activate my software. I need to pay?

I have a also a FLX6, FLX4 and DDJ400. It complicated me, that I chose VDJ as software.

Thanks for your help.
