I'm not sure if this would work but maybe a cloud service is in order. Pay a fee and use your activation code as a password to the cloud. You would DL everything but the RTs and RDs. You would then use the cloud as you would an external HD. If you didn't upgrade the next year those RTs and RDs would not be accessible with your code.

This would help the user but probably be a big PITA for PGMusic! They would need to have enough cloud space and monitor it. But it is a thought. YMMV

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
