I've used PP Shipping many times in the past. Now, however, it won't let me, saying, "Your payment for shipping cannot be processed because it exceeds your available balance. Please add a credit card or bank to your account for completing this label purchase. ERRORCODE-50023". BUT I DO, AND ALWAYS HAVE, HAVE A VALID BANK ACCOUNT LISTED AS MY DEFAULT PAYOR. Any advise? I DON'T want to go to the PO, and USPS won't let me print First Class mail.
