I've been using Antivirus 2010 and had about a week of my subscription to go. I purchased Antivirus 2011 and uninstalled the 2010 version. After installing the 2011 version from the disk I purchased, my subscription still has only a few days to expiration. I was not asked for the new product when I installed 2011. How do I get this recognized as a new 12 month subscription?
