OK, I was able through trial and error to get the card changed. Explicit instruction should be given though, for dummies like me. Hopefully this will help others:
- Go to My Account –> Payment Methods and at the bottom click Add Payment Method (credit card or Paypal) Active subscriptions will not be affected, but those on auto renew will go to the new payment method after doing the steps below.
- Go to My Account –> My Subscriptions
- Click the Subscription Number
- Under Subscriptions Number details in the Actions line, click Change Payment
- By default the new Payment Methos will be chosen and you will need to enter the card security code
Thanks
