I'm trying to buy kontakt 7 and do it through the crossgrade price to save 100 dollars. It says I do not qualify for cheaper purchasing even though I have two of the plugins that are eligible for crossgrade pricing. I have both Vintage Organs and West Africa. They are both the full version and run in the kontakt player, I have serial numbers for them on native access. Should I just go ahead and buy the cross grade anyways? I don't want to buy it and not be able to run it.
