I get this message:
Uh oh... that shouldn't have happened.
It appears you've found a glitch in the system.date: 2012/12/17 01:34:36 PM
My credit card was recently cancelled and replaced with a new one, so that might be the cause. I already added the new one but can't remove the old one and xbox live won't let me connect, telling me to update payment options every time I log on, and giving me that message when I try to update the payment option.
