Tried to pay by CC 6 times and kept getting this error: creditCardInfoModel.payCCNum(value: null) may not be null; All CC data was correct. What caused this? --Tom

Used a MasterCard, verified that the CC number and security code were both correct, card was valid (Not expired), and had sufficient available funds to pay the full bill.  Also verified the billing information (Name, address, etc.).  Had to spend the $39.99 to pay with my Federal refund.
