i was using Pc-cillin internet security 2005, i've stopped using it about a month ago. the problem is the serial # is supposed to be expired on 2/15/2005 but a month ago it kept saying that the serial is invalid every time it tried to update. it doesnt matter how many serial # i tried, it still ended up with the same problem. i even tried to reinstall it but the problem is still not solved. any idea why?
