Minecraft seems to disable the NSM service. NF not tracking/enforcing time limits on PC

Greetings all! My son plays a lot of Minecraft. A couple of months ago, we started having a problem with NF just shutting off while he was playing and not enforcing the House Rules. When I looked at the services running, NSM was listed as being turned off. I even set up a batch file to restart the service every 30 minutes or so, but to no avail.

I've researched the internet to see how Minecraft might be conflicting with NF but have found nothing. And yet, NF is still being disabled. Any ideas on how to resolve this issue?

Many thanks! - Jeff
