Of course, clicking on the provided link takes you to an error page that says "Invalid Request." How do you update you payment options of you can't log in to your account? Here's how you fix it:
Put the following URL in your browser: https://admin.google.com/DOMAIN.com/ForgotAdminAccountInfo . Replace DOMAIN with your own personal domain. You also need to replace .com with .net (or .org etc). This will take you to a Captcha screen. After typing in the captcha, Google will send an e-mail to you with reset instruction. Follow the link and fill in the information. You will need to update your payment options.
You can also probably fix this, though I have not tried it, by logging into your domain's primary e-mail account at bloggeradmin@DOMAIN.com (or .net, .org, etc.).
