Norton Antispam Outlook Plugin and the toolbar in Chrome is gone

I have Norton 360  installed on a Win7/64 PC. Using it with Outlook 2007. The Norton Antispam Outlook Plugin (toolbar) was working properly up until just about some  week ago. Suddenly the toolbar in Outlook disappeared. I can't seem to re-enable the plugin -

 

And the Norton Toolbar in Chrome is gone too.

 

 

Any ideas as to what might be causing this?
