Just applied Norton Internet Security patch via LiveUpdate; NIS missing from taskbar

I'm using Windows 8.1 and just ran a LiveUpdate on my system. After the updates downloaded, I was prompted to apply the patch, which I did. No problems; Norton Internet Security appeared in the taskbar after a short pause. However, after rebooting my PC, the Norton Internet Security icon doesn't appear, and nothing happend when I try to load it from the list of programs in Start. I have tried several reboots and still get the same issue.

 

Anyone else experiencing this?
