Error CC-503 when adding new CD account at Lending Club

Carl S

I have a Lending Club account already connected to Quicken and IT IS WORKING JUST FINE, However, when I try to connect a new Lending Club CD account, I receive a CC-503 error and this message, "We can't add your account because Lending Club is telling us that your logon is incorrect."

I've tried everything procedure recommended by Quicken support. Starting from scratch, connecting after manually setting up the account, resetting accounts, etc., etc. I called Lending Club support and they claim it is a Quicken problem. HELP!
