Run as administrator

The quickest way to resolve this is to run the Sage MTD Submissions Module as an administrator.

Rename the MTDBridgeCredentials and Entitlement folders

   • C:\Users\<<<USERNAME>>>\AppData\Local\Sage\SageMTDBridge 
5. Right-click the MTDBridgeCredentials folder, select Rename and rename to MTDBridgeCredentials.old. 
6. Repeat step 5, renaming the Entitlement folder to Entitlement.old.

7. Re-open the MTD module and enter the correct details. The module serial number often begins with the letter 'M'.
