Cairyn has it correct. You have an MSA contract with a reseller that auto renews. The last auto renews that will renew are from (mostly) European distributors and resellers in September and October. Assuming you didn't cancel it, it renews. MAXON and resellers have the same cancelation policy as you, we need to cancel the next renew 3 months in advance. If you have an MSA that renews you will get R21 perpetual (already delivered) to keep. If your MSA extends past our next perpetual release you will get that as well.
