LiveUpdate: Operation Failed and continuing problems.

I had to reinstall Norton 360 after some sort of failed update that asked for the program to be uninstalled and reinstalled (something my mother did that I know nothing about).

Because her desktop still had an icon saying "Install Norton 360 version 2," I decided to click that to install and then update the program.

Problem now is that LiveUpdate will not run.  
I try to run it, and it says "Operation Failed."

I tried the Symantec Intelligent Updater, but it also failed in loading updates.

What do I do now?
