Please enter a valid credit card number. – как исправить?

I have double and triple checked and I AM entering my *** card numbers in correctly when I try to add a new card to my account.

WTF? I am close to giving up with this…

Start with our Payment Method guide and post back if you have any further issues: forums.xbox.com/…/19164.aspx
