Hi Chris,
Thank you for trying the troubleshooting steps in this thread.
If you haven't already, you can repair your QuickBooks to fix any damaged file components that might have caused the expired password issue. However, if you continue to receive the same thing, please contact our QuickBooks Desktop Support, so they can use more tools like screen share to check this further. You can find their contact details in this article: Contact QuickBooks Desktop Support.
Let me know if you have additional questions. I'll be happy to lend you a hand.
