about Rekordbox purchase

I bought an sx2 controller from someone and as a result I had no choice but to purchase the rekordbox pro software.
Now I sold the sx2 controller I had and instead I bought a more advanced rz model controller. I looked at the table on the website and saw that I deserve the rekordbox pro software.
Can anyone answer if I cancel the program I purchased and connect the computer with the rekordbox software to the controller, will it pass to me in the pro version without having to pay or do I have to continue paying?
