Norton 360 v5 updated, but several softwares can't access internet

HELP!!!!   Except for Outlook, my Office 2010 software and others cannot access the internet, which means I can't  register online or access Office 2010 online help.  Also, no matter how I configure the firewall settings via Custom or Allow for Norton 360 (v4 or now v5), several items will not connect:

 

Office 2010 64-bit

iTunes (latest version)

Amazon Unbox for video downloads

Internet Explorer v. 8 (Firefox DOES work, thankfully)

And, sometimes, even Norton 360 will not connect to the internet...

 

so what is going on?

 

Thanks for any help, janfrel
