I take it you are referring to the Norton Settings you cannot access? And you have set up a Settings Password?
Any information you may have found about resetting the password no longer work. I have brought this to Norton's attention a couple of times with no luck yet. I'll get your thread escalated.
You could try reinstalling Norton by first using the Norton Removal and Reinstall Tool using the Advanced Remove Only option. www.norton.com/nrt Then restart your computer and log into your Norton Account and download a fresh copy of your product. Be sure you run LiveUpdate manually a few times, restarting as necessary, until no updates are available.
Hopefully that would reset/remove the password.
