1. In the Edit > Preferences > Quicken ID Sync & Alerts section, click the blue link that says “Sign in as a different user”.
2. A window will open asking you to confirm that you want to sign out, type “Yes” in the box and click OK.
3. Quicken will refresh and show a blank sign-in screen, when it does, close and re-open Quicken.
If the trouble persists, I would contact support for more advanced troubleshooting.
Thank you,
