I'm using Quicken Classic Starter on Windows 10. Quicken has been updating Capital One Credit Card and Savings just fine until October, and then it started displaying the CC-506 for the savings account. I have the latest release. I have not closed the account. I tried the deactivation/reactivation for just the savings account, but it didn't change anything as Quicken only "sees' the credit card. I tried deactivating/reactivating both accounts, but same result. So I am following the "Contact Quicken Support for assistance. Your financial institution cannot resolve this issue." path now.
