Keep getting a message my subscription has expired for NIS 2011

...even though I just renewed and my subscription status says I have 377 days remaining.   When I click 'renew' to reenter the product key, everything goes as it should (the ending pop-up window says I have the correct number of days remaining, but the NIS dashboard doesn't refresh to reflect this and stil has the red banner saying "Subscription Expired Your computer is at risk!"
