suddenly unable to access account

I installed Norton Online Family on my computer several months ago. Suddenly, I'm not able to access my account--it's telling me my email/password is invalid. In fact, now when I go to the online family home page, it invites me to create a new account.  It appears that the old account is no longer active, and yet it is still blocking the sites I programmed, and I am getting the messages in my master email when I try to access them.  What is going on? I can't uninstall because it's not recognizing my password.

 

I'm wondering if this is because I let my regular Norton Security account lapse? I've re-subscribed, but still having this problem.
