I installed NIS 2009 on my computer and my wife's laptop. My problem is outlined here. Yesterday I was checking my wife's computer and I noticed Firefox would not work and after upgrading Webroot Spysweeper it would not connect to the internet either. I tried to open NIS 2009 and it had stopped working. I used the NRT to remove it and then I reinstalled NIS 2008 and entered the code from 2009 to continue my subscription. On my other computer NIS 2009 first attacked firefox before it went bad. I hope Norton is able to fix the issues with 2009, but if not I am very happy they allow you to revert back to 2008 and use the subscription for updates.
