I may have actually figured out what was happening here. I had about $200 in my account yet I kept getting ERRORCODE-50023 and couldn't purchase a label to ship an already paid item...I went to my PayPal WALLET and realized I somehow had *nothing * selected for "preferred way to pay online". I simply selected my PayPal balance as my preferred way to pay online (instead of inexplicably having none of the options selected?) and I was then allowed to purchase and print the label. I believe the error code is coming because when there is no preferred way to pay online selected, then it thinks there is no money and it prevents you from purchasing . Hope this helps somebody!
