We got you, @kylel821. We understand the inconvenience it has caused you. We are here now to provide the troubleshooting steps to help you fix the error you've encountered.

Difficulty in accessing your company file can cause the following error when you try to open or use QuickBooks desktop (QBDT). We can run the Quick Fix My Program from the QuickBooks Tools Hub. This program is a collection of tools that can assist users in fixing serious problems and difficulties they may encounter when using QBDT. We advise using this program on Windows 10, 64-bit, for the best experience.

Here's how:

1. Close QuickBooks.
2. Download the most recent version (1.5.0.0) of the QuickBooks Tool Hub.
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install, then agree to the terms and conditions.
5. Double-click the icon on your Windows desktop to open the tool hub if the installation finishes.

After that, you're now ready to run the Quick Fix My File and QuickBooks File Doctor utility:

1. From the tool hub, select the Company File Issues tab.
2. Select Quick Fix My File.
3. Once the process is completed, click OK and then open QuickBooks again.
4. If you're still receiving the same message, go back to the tool hub, then click the Company File Issues tab.
5. Select Run QuickBooks, File Doctor.
6. Choose your company file from the drop-down menu.
7. Select Check your file (middle option only), then click Continue.
8. Enter your QuickBooks admin password, then hit Next.
