subscription ver 6

Dear recordbox software developers. I bought Rekordbox video and Rekordbox DVS licenses. Will the old version of the program be supported? Subscription is a mockery of people who bought your software, because Rekordbox Video remains a raw product and does not have stability. I bought it in the hope of correcting errors. I also have a PURCHASED DVS license, which now does not work in version 6. It turns out you do not intend to fix errors in version 5 of the program. I have a DDJ-1000 that supports dvs, for which I bought a license. Now I have to buy the whole subscription for dvs. What do i do?
