Hi there, @pamij.

I appreciate the specific details you've shared. This error means that the data has been damaged. I'd recommend using the QuickBooks Tool Hub again. Before that, you'll have to update the QuickBooks Desktop version. This is to make sure that the process will go smoothly when running the tool.

Here's how:

1. Go to the Help menu and choose Update Quickbooks Desktop.
2. Select the Update now tab then, click Get Updates.
3. To finish the update, you can restart the QBDT program.

Here's how it looks like:

After that, you can check this out this article to know more about the steps on how to use and download file doctor: Fix company file and network issues.

If the error is still there, you can proceed to Solution 2 and 3 in this article: Error: -6144, -301 when opening a company file or restoring a backup.

Also, the articles that I've provided to you are tagged as United States since QuickBooks Desktop is only available in the US, Canada, and United Kingdom. No worries, this has the same product specifics except for the taxes.

You are always welcome to tag my name in the comment section below if you need further assistance or concerns. I'll be here to guide you throughout. Take care.
