Hello everybody it's me again, there is a problem with when I try to purchase something with a credit card on the 360. I am trying to purchase 1000 MS points, but when I try to, it gives me the message "Cannot authorize the selected payment option. Please select a different payment option or add a new one." I have used this one to buy my membership with, but even if I try to add a new credit card it gives me this message when I try to finalize it. If it matters I'm doing this in Halo 3.
