An error of this kind is generally due to security features on your card blocking our system. Please contact your bank to determine the cause of the block (we cannot see this information from our end). Please also make sure to let the bank know to accept charges from Udacity.com.
If this does not resolve the issue, please send us a message detailing your bank's response, and we can proceed from there.
