subscription is due to expire unable to initiate upgrade

Getting a notice that my subscription is due to expire in the next couple of days. When I try to update and/or add account information, I continue to get a response, "We are processing your order, please check back later and if this continue to occur, contact support. However, I have not set up a subscription since my first year was free. How can I upgrade if it doesn't allow me to change and/or edit the account?
