Thanks for taking the time to address the problem, dmroberts2. I’ll help you avoid the error you’ve encountered and make use of the bank feed section in QuickBooks Desktop (QBDT).

Please know you can utilize the QB Tool Hub to address the license and registration problem you encountered heading through the bank feeds. But before doing so, you'll want to set it up. You can follow these steps:

1. Close QuickBooks.
2. Download the most recent version  (1.6.0.8) of the QuickBooks Tool Hub to get the best result when using the tool. Save it somewhere you can easily find it 
3. Open the file you downloaded (QuickBooksToolHub.exe).
4. Follow the on-screen steps to install and agree to the terms and conditions.
5. When the install finishes, double-click the icon on your Windows desktop to open the tool hub.
6. Select Installation Issues, then click 3371 Error Fix.
7. Click OK.

If you don't see the icon, you can utilize the Window's Search bar, and enter QuickBooks Tool Hub. For further guidelines, please see this page: Fix common problems and errors with the QuickBooks Desktop Tool Hub.

Once done, access QuickBooks and see if the bank feed section is usable. If needed, you can also get rid of the registration file and utilize the steps provided by our colleague above. We also recommend checking this article to help you address licensing issues: Fix activation, license, and product numbers issues.

If you continue to experience sync license data errors, you can also manually rename the entitlement data to solve the problem.

Here's how:

1. Open the Windows Start menu.
2. Type in "Run" into the search and open Run.
3. Type C:\ProgramData\Intuit\Entitlement Client\v8 and then Enter. If this doesn't open a folder, enter C:\ProgramData\Intuit\Entitlement Client\v6 instead.
4. Find EntitlementDataStore.ecml. Right-click on it and select Rename.
5. Rename the file to EntitlementDataStore.ecml.OLD.

Once done, open QuickBooks and your company file and register it again. 

After successfully importing the bank transactions, here's an article that will guide you in assigning categories to them: Add and Match Bank Feed Transactions in QuickBooks Desktop.
