I just tried to purchase the license for MC18 at the pre-release price, when I clicked to purchase, it charged me full price (I didn't complete the purchase). I think there was some fix for this somewhere, but I couldn't find it. I entered my 25 digit registration code instead of my 6 digit access code, which is what I thought was requested. I tried it twice, in case #'s were incorrect, they were and I got the same result. Spending full price to upgrade would be insane-I'm actually happy with it as it is, but for not-too-expensive a price, I'd be curious about the upgrade.
Thanks
Jack
