I bought the upgrade, and JRRShop emailed me a license code. The code is 32 characters long, but it doesn't resemble a Cakewalk serial number, at least that I can tell. When I try to register the code on the Cakewalk website, it says it's not a valid serial number. I've emailed customer service at both Cakewalk and JRRShop, but I'm still waiting for an answer.
Does anyone have experience with this sort of thing?
