Got this message today so I tried adding a new card and kept getting that it wasn't a valid CC number on both xbox.com and my console. I then got annoyed and just bought a 3 month subscription card and tried entering it on xbox.com...every time I try this I get this "An error has occurred during the transaction. Please try again later." I said okay maybe something is just wrong with xbox.com and tried it on my console and I got some stupid error code "80169D3A." I really don't know what to do at this point.
