NIS icon missing from tray after 16.7.2.11 update & Windows updates

I have NIS 2009. Last night I got the new 16.7.2.11 update & everything seemed fine. This morning my computer downloaded & installed the new Windows Updates. Now the NIS icon is gone from my tray & I can't get it back. I assume this must have something to do with the new Norton patch and the new Windows updates. The NIS icon is still on my desktop and in my start menu. It still appears to be working fine, except it's gone from my notification tray. When I right click my taskbar & check properties, the icon is missing from there too, although NIS is listed twice, with no icon beside it. Does anyone have any idea how I can get it back?

 

I am running Vista Home Premium 64 bit.
