I had 55 days remaining on my subscription. I read on the Norton web site that if you renewed that they would add the existing days onto the 366 days when you renewed. I downloaded the new NIS 2012 and entered my new code. Everything went well except when my Norton came up after all was said and done it said I had 366 days left. It should have added my previous 55 days that I had left onto the 366 for a new total of 421 days.
