Serial number not accepted after purchasing LightRoom 5
I downloaded the 30 day trial of LightRoom, LightRoom Mobile and Creative Cloud, then decided to buy outright LightRoom 5 from Amazon (not wanting a monthly subscription to services I didn't need).
I got a serial number from Amazon, downloaded and installed my purchase and tried to enter the serial number. I got a screen message saying the serial number is invalid.
How can I fix this and activate what I have paid for?
BTW, why do I have to query a forum instead of getting advice from Adobe, who presumably have my money?
