Let me join this thread and provide a different suggestion, Tim. 

I would recommend contacting our Technical Support Department. They have additional tools that can check why you're still getting the error even after following the recommended steps. 

Here's how to reach out to them:

1. Open this link: https://help.quickbooks.intuit.com/en_US/contact.
2. Select QuickBooks Desktop, then select the version that you're using.
3. Click Solving Issues and Error Messages.
4. Click Common Errors, then click Get Phone Number.

You're can visit us again in the future if you need help while working with QuickBooks.
