So I have a dilemma. I upgraded from FCP 1.2 (yeah yeah) to FCP X and it was the absolute worst piece of crap I had ever tried to use. I would now like to downgrade to FCS2 but wanted to check one thing before doing so. Will I be able to use my serial from FCP 1.2 as the upgrade serial to install FCS2 Upgrade? Is there a most recent version I must have to make the upgrade work like Adobe does with their Creative Suites?
