Norton 360 reinstall

Yesterday I formatted the hard drive of my netbook.

 

Then the first thing I did was to install Norton 360 and entered the registration key (that is still valid for the next 38 days). I did the update (it has downloaded about 350MBytes and shown the indication of 38 days to renew the license).

 

After installing Norton I start the windows updates and since normally that takes ages I left it on overnight. For my surprise today Norton was "red" indicating that the license had expired... I managed to put it right after running twice the "live update" but I do not know for how many hours it was like that!

 

 

Do you know why it happen?

 

Thanks,

 

Alex.
