Norton not updated in 32 days

Twice in the last two months Norton Internet Security tells me that it has been 30  days and 32 days since the last update, even though LiveUpdate says it recently ran (in the last several minutes).  I clicked on the update button and a large download occurred.  I did not write down the size of the update but it was over 300 meg.  SETTINGS shows Automatic LiveUpdates, Pulse Updates and Automatic Download of New Version turned on.

So I don't know if I need some education about how to set up updates or if there is a problem with LiveUpdate?

Thank you in advance for any help you can offer.
