Capital One: Error 501/107 When Adding an Account
This error occurs when the wrong instance of Capital One is selected while adding an account to Quicken. Example: Adding a Capital One investment account but selecting Capital One Card Services as the financial institution. Note: In Quicken for Mac, the error will appear as 107 instead of CC-501.
To resolve this issue:
You will need to start the Add Account process again and select the correct instance of Capital One for the type of account you are adding.
