Problem with Norton Security Suite

I have been using Norton Security Suite that I get from Comcast, My ISP with Windows XP Pro.

The other day it quit working all of a sudden. I reinstalled it (several times) after uninstalling it.

It continues to require me to activate it each time the computer is booted. Other than that it works as expected.

I can't figure out how to fix this issue and don't find much about it searching the internet.

Any assistance would be much appreciated.

Mike.
