While updating my virus definitions file, the dialog box appeared indicating my subscription had expired. I accidently selected the wrong option ("I do not want a subscription" or whatever) and now I cannot go back and purchase a subscription. At the end of running live update it tells me my subscription is expired but I do not see any option for me to purchase it. If I go to the Norton store the only option for purchasing a subscription is for NAV 11. Is this compatible and if so how can I get NAV to ask me for a subscription key?
