Hi,
clearly Mach is of the opinion that you have a motion controller device and without a licence file it will
operate for only six minutes as you have discovered.
If there are no motion controller plugin in the plugins folder then it should run without limit. Have you, at some stage,
had a motion control plugin in the plugins folder? From your description it sounds as if you have and Mach still thinks
that is the case.
As I posted earlier I had Mach4 operating on my laptop (development PC only) for some time and it would run without time limit.
Once I loaded the ESS plugin, not even as the selected motion controller, but just as two unused files in the plugins folder THEN Mach would
operate for the limited time.
