Hello @Willis Sinclair,

Let's download and run the QuickBooks tool to fix the issues with accessing your company data.

1. Download the QuickBooks Tool hub.
2. Open and install the downloaded file.
3. On the QuickBooks Tool app, select Program Problems.
4. Click Quick Fix my Program.

But if you already perform these steps with the same results, you'll want to repair the QuickBooks itself.

1. Go to Start.
2. Select Control Panel.
3. Under Program and Features, select Uninstall a Program.
4. From the list of applications, select QuickBooks.
5. Select Uninstall/Change.
6. Click Repair.
