Control Center gets a blank page or cannot load data due Service stop : Inèdit Software

Problem

I try to start Control Center from neoStampa but I get a blank page or a loading forever one.

1. Identity which of the services is not running:

Try to reach neoControl from a web browser. E.g.: If the browser shows the neoControl page localhost:49098, it is fine. If not, is neoControl the one that is not working?
You can check also if Control Center is running in e.g. localhost:49373.

2. Open the Services app from the Search menu or Task Manager in Windows.

3. Stop the "nS ControlCenter 10" service on the Services application or from Task Manager.

4. Go to C:\Users\Public\Documents\neoStampa 10

5. Rename the Queue Manager folder to, for example, "_QueueManager".

6. Go back to the Services.

7. Search by "nS ControlCenter 10" and start the service.

8. Make sure that the service has the Status "Running" instead of "Paused".

9. In neoStampa start Control Center from the button or web browser URL http://127.0.0.1:49373

10. Go back to Control Center and you should see the data loaded.
