This may mean that the associated payment option doesn't match the region of your Xbox Live account. For example, if you have a US account, you cannot use a payment option (such as a credit card) that is registered to an address that is outside the United States.

To resolve this problem, try using a payment option that corresponds to an address located in the region of your Xbox Live account.

If you keep experiencing the problem, contact Xbox Support.
