Get a copy of "datehack". Run it, select "change date", update NAV, select "restore date".
I agree that you should not expect something for nothing, but finding hacks and cracks is part of the fun of the web. If I don't find it, I buy it or don't get it, I don't whinge on about it.
However, if you but a copy of say, Half-Life, It does not expire or stop you from patching it after a set time. Think about how much more work goes into this game which costs roughly the same as NAV.
Norton are just protecting themseleves from redundancy - not protecting you. I paid for the software and I want it to be useful for ever if I can get it.
No regrets.
