My previous version of NAV for Mac was up for renewal. I saw that Norton now had a bundled product (NIS for Mac and NIS 2010) for both Mac and Windows-I run Bootcamp for non-Mac websites. I was told by a techie at CompUSA that I could install with no problem. I installed both products. I was running a free version of Antivirus on Windows. After installing I was unable to run liveupdate. I contacted Norton and was put in contact with a Tech. I ran the Norton uninstall software, reinstalled, and the Tech made some changes on my system. When i ran liveupdate, It showed no updates at this time. I ran this for a while with no updates. Recently i am getting a message showing that my NAV subscription is out of date and it asks me to renew. Not sure what to do at this point.
