My product key not working anymore after reinstalling NS

Hi,

So my situation is this. Before reinstalling Norton Security I was using NIS which is updated to Norton Security. Why I make reinstallation? Because liveupdate broke down and always gave me update failed error. Now when I am try put my product key back I got only message The Product Key entered is not valid for this product. (-1002). So NIS keys are not anymore working with NS?
