Automatic pulse and live updates stopped working!

Hi,

 

I'm new here, but not new to using Norton Antivirus. I had no trouble with Norton Antivirus 2010. Purchased the CD-ROM for 2011, and up until recently, it appeared to be working fine. With a subscription status of 322 days remaining, I got a notice that the virus protection was out of date and then realized that the updates do not work on automatic. No changes or adjustments/settings have been made. My computer has Windows XP with Service Pack 2.

 

How do I fix this problem? Any help is greatly appreciated.

 

TIA
