Hi there, @Carolina99.

As mentioned by my colleagues above, errors usually occur when the QuickBooks data is damaged. Or the company file can't be read correctly by QuickBooks. And to fix this issue, you can install the QuickBooks Tool Hub and resolve the file from there.

To repair your company file using QuickBooks File Doctor, kindly follow these steps:

1. Close QuickBooks.
2. Download the most recent version (1.5.0.0) of the QuickBooks Tool Hub (if you haven't already). 
3. Save the file somewhere you can easily find it (like your Downloads folder or your Windows desktop). Note: If you've installed Tool Hub before, you can find out which version you have. Select the Home tab. The version will be on the bottom.
4. Open the file you downloaded (QuickBooksToolHub.exe).
5. Follow the on-screen steps to install and agree to the terms and conditions.
6. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.

Then, run the Quick Fix my File tool. Here's how:

1. From the tool hub, select Company File Issues.
2. Select Quick Fix my File.
3. Select OK when it completes and launch your QuickBooks.

If you still get an error message, continue with the troubleshooting steps starting with Step 3 in this article: Fix company file and network issues with QuickBooks File Doctor.

If the error continues, you can utilize the  Rebuild Data tool. It's a built-in tool that can help automatically fix data issues with your company file. For the step-by-step guide, please see this article: Fix data damage on your QuickBooks Desktop company file.

Please let me know if you have additional questions about this or anything else. I'll be more than happy to help. Take care always.
