Norton Antivirus Renewal

I renewed my Norton Antivirus subscription on Nov 10th after it expired.  It was expired two days before I renewed.  I received a confirmation and an order number.  However I did not receive a new product key to activate.  I have been unsuccessful in activating so I am still unprotected.  Now, whenever I click on my account or on the renew button on my Norton window, all I get is a message to "buy now."  Help.  And Thanks.  Kim
