2012 Norton Internet Security not working

I think that my Norton Internet security software is not working.  I have the 2012 version which expires on Sept/10th. Google Chrome has indicated that it has crashed.  I click on my Norton Icon on my desktop and nothing happens, previously this would allow for scans, updates, etc.   Also when I run the Norton  link  on the update center  a message comes back that "No Norton product was found...We're sorry, but we were unable to find a Norton product on your computer."

I'm not sure but it seems that about a couple weeks ago after I clicked on an alert option to update my norton, problems seem to have started. 

 

What can I do? Should I uninstall and try installing again? I have one more download.
