I have Norton Internet Security 4 for Mac running on an iMac PowerPC on OS 10.4.11. Everything had been working fine, but for the last week or so my LiveUpdate will not update. When I run it manually, the window comes up that reads "Determining what's available" but nothing updates. Then the LiveUpdate Summary box opens like it has already updated and shows that everything is up-to-date.
Any help is appreciated.
