Subscription Warning on brand new install

I just yesterday purchased and installed Norton AntiVirus for Mac version 11.1. It was running an old version of LiveUpdate, so I downloaded and installed v 5.1.2 from the Norton site. Now, when I run LiveUpdate, it tells me my subscription will expire in 3 days, but I should have a 1 year subscription at this point, because I just purchased the new product. I can't find a key code anywhere on the User Guide or installation card that came in the box.
