Good Morning,
here are more Users who talks about that Problem with the LiveUpdate and “You are offline”
With Norton 360 v.22 or v.23 i don´t know anymore i had installed Norton VPN that was included to Norton 360, but here i never had it activated and LiveUpdate works with a manually Check and Update over the Button. (we don´t talk about the Automatic LiveUpdate that works fine in both Versions v.24 and 2 or 23).
