Entered AVG AV 2015 license #, was told 'temporary" ?!

Hello Bob. I have checked and can see that you have tried to use the sales number which has only 30 days validity. You need to change the sales number into full license number. Please click on the following link to convert to full license number  :http://www.avg.com/us-en/registration . If the issue persist, Please contact us. Thank you.

I bought a copy of AVG AntiVirus 2015 in June, knowing that my son would need it in August.  It was a download copy.  I received an email from AVG with the product license number.  My son tried activating the license, and he tells me (by phone) that the license number he entered (which I received from AVG) is "temporary".

OK.  What's my next step?  The SW was purchased from Newegg.

THANKS!
