NIS 2010 keeps making me activate it every time I reboot

My NIS 2010 subscription is good for 205 more days, but every time I reboot the machine (Windows 7 Ultimate), NIS says it is "At Risk", and that my subscription needs to be activated.  I click on the "Activate" button, and then it goes off and successfully activates.  This started happening about a week ago, and now every time I reboot, I need to do this.  What is going on?
