First login and then type in the Search box "services" and click on the first option that appears
Once you click on the services program you should see the below window appear
The list will be in alphabetical order and under 'B' you should see "BEAMS" listed. As show in the pictures the service is started however when i attended to your issue it had a blank status meaning it is stopped.
Right click on the beams and click "start", in the picture below it is greyed out but that will not be the case if it has stopped.
