Norton Antivirus - update problem ?

I had a trial version of Noton antivirus 2006.I then got Norton antivirus 2005(1 year subscription).(I then removed the old Norton antivirus)When I open the main page of the new antivirus, the renewal date comes as 3/3/2007. But when try to update my virus definition it shows that my subscription has ended on 17/11/2006 (my trial version's subscription had ended on this date).How can I solve this problem and update my Antivirus.

THIS IS URGENT .MY COMPUTER HAS ALREADY BEEN AFFECTED BY SOME VIRUS AND THE NON-UPDATED ANTIVIRUS IS NOT ABLE TO FIND THE VIRUS.

It better that u use ur previous version i.e.2005 (if ur having full version) i'm too using the same, and gets updated easily. The thing is that all the contents of NAV 2006 come in this, only name doesn't change........
