How do I get my NIS multi-use license onto a new laptop that came with a 30-day 2009 trial?

I have a 2011 3-computer NIS license, but my new laptop came with a 30-day trial of 2009 NIS which I activated thinking I could upgrade it.  I can't get Norton to recognize that I want to put the license onto this computer, it keeps insisting I need to pay to get a year of an inferior product, and will not give me a screen I can enter the product key on.  Help!
