On January 13th (poor choice of days) I bought a new computer and moved Quicken. Now I have seven accounts that won't attach, four of them credit cards (2 Mastercard, Amex, Visa) and three of them bank accounts, but all with a CC-503 error message. I've been able to log online with every one of them using the same credentials CC-503 says are errors. I've used Quicken for over 20 years and know and have tried all the workarounds, resetting my cloud data, deleting my cloud account, signing out and back in, then re-adding my cloud account, plus three super validations. I've also checked the password vault and none of the logins are there. I'm at a loss as to what to try next. Please help before I pull every last hair out of my head.
