Transfer AVG subscription to new computer

This is what I tried but before it downloaded it asked for a product number (from a booklet or disc) which I did not have since I originally bought it online.

I bought AVG Internet Security 2013 (2 years) and AVG PC TuneUP and am unable to transfer to my new computer.  I tried the download and put in my license # but it also asked for a product # which I do not have.  How can I transfer this subscription to my new computer?

At this time I have downloaded the trial subscription to AVG TuneUp but that's all I have.
