Norton Protection Center does not recognize 2009 Norton Antivirus installation

Norton Protection Center keeps telling me that I have no antivirus protection intalled, when I just installed Norton Antivirus 2009, ran Live Update in both Norton Protection Center and Norton Antivirus 2009, and restarted the computer after each Live Update. 

 

I read the previous post about this subject, but the thread went so far off the main subject that I quit reading.  I thought I followed the directions given to fix this early in that post by running Live Update and restarting, but it didn't work.  Any help would be greatly appreciated, since I am tired of Protection Center telling me that I have an urgent problem.  Thanks!
