I have spent 20 minutes looking for the credit card update, with no luck.

Hi Duncan,

Try this:

1. On the My Accounts page, under the Profiles heading, select Upgrade/Renew Existing Profile.
2. Select the profile(s) for which you want to update credit card information. Click "Continue with Purchase".
3. On the Purchase Membership (Confirm) page, click on "Continue with Purchase".
4. On the Purchase Membership (Confirm Order) page, enter your credit card number and click "Submit Payment Now".

Hope this works for you. - RT

Thank you Robin. A more circuitous method than I imagined, and it negated auto renewal, but it worked! Guru should really get with the times and provide a simple way to update this information.
