[UPDATE 25 April 08, 3:40 pm Pacific]
Our payment processor has fixed and tested the process. All card operations (including updates) are now running within normal time frames.
Due to an issue with our payment processor, we are unable to update your credit card information at this time. Attempting to delete and update your credit card will be indefinitely delayed. You may enter card data but it will not be active in our system for potentially several more hours .
If you have valid credit card or payment information, you can continue to USE it with no problems- this only affects updating card information, or initial card data entry.
Updating Paypal payment information is completely unaffected.
We are working with our payment processor, and credit card updating will work as normal as soon as their issues are resolved.
