Upgrade 3.1 to 3.2

Where do I get an unlock code to go from a licenced version of V3 to a later version of V3 (V3.1.0.457 to V3.2.0.603)?. I installed it but the unlock code apparently only works once. So I can’t go back. I am ready and set up to run this evening and SGPro has stopped me in my tracks. Anyone any ideas?

SGPro does not use one time unlock codes. The issue you are experiencing is because we migrated to a different licensing system in 2020. We sent out emails in advance with instructions. It’s reasonable to expect that you may have missed it though. We can re-send you these instructions if you email us at support@mainsequencesoftware.com so that we can find your existing account.
