Not accepting the Norton AntiVirus 2006 activation key?

Alright, I just download a LiveUpdate thing, and when I restarted my computer, it said 'my free trial period has ended'. I tried activating the program with the program key that I found on my computer, but it doesn't work.

It says ''There is a problem with your activation key'

I do not have the CD for the program, because we bought the computer with the program installed already. What should I do?

I'm using Norton AntiVirus and Norton Protection Center, both the 2006 series.

Your free trial has expired coz it happened to me too. You only had a certain number of days for the trial. Now you need to purchase a new anti virus for your pc.

The new Norton is 2007.
Try to use Spybot S%26D(free antispyware), and AVG or NOD32 antivirus. I'm using NOD32 and Spybot for few years and never had any damage on my comp.
It cannot accept the product key because the software's free trial period has ended, and you cannot update until you renew your subscription with Norton.
There is a difference between a Product/Program Key (and other aliases) which you might find on the 'About' page of a program, and an activation key. As a rule, activation keys do not remain stored.
