HELP!!! Updated to Norton Internet Security 2011 and now Outlook will not open

I just updated to Norton Internet Security 2011 and now my Outlook will not open... it almost does (briefly shows Outlook screen) but then closes and gives simple message of "Cannot start Microsoft Office Outlook.  Cannot open the Outlook window."  Since everything worked fine until I let the Norton Internet Security 2011 be installed & activated, I'm assuming that this subsequent Outlook failure to open is due to this update.  

 

Anyone else run into this???  Anyone know how to fix my outlook??
