Novkhan, Try Here for Symantec's online Subscription/LiveUpdate help.
I hate to say it but I don't think there's a way around having to deal with Customer Support.

You got to remember Novkhan, if it were that easy to just change some parameters in the registy in order to 'un-expire' Norton via date change, well, I think they would have gone belly up financially as no one would ever need to purchase yearly subscriptions anymore .
