I was having a look on Norton site yesterday to see if I could keep my days left on NIS 2007 if I upgrade to NIS 2008. I noticed that with 360 they said that you would lose them.
When I upgraded from 2006 to 2007 I spoke to an advisor and she did add the days for me.This has meant that my subscription is still running well after the 12 months. With this in mind I sent an email asking if this could be done if I upgrade to NIS 2008. Despite several emails they insist that my sub. ran out last November,but my NIS says I still have 121 days remaining! I shall just wait until they run out.
