Thanks xdubber, turning off password protected sharing did the trick. And why couldn't Milltronics have suggested that? Oh yeah, they don't use Win 10. As for using Windows 10 in a business environment, it shouldn't be a problem. All may customers use it. I've been using it for a couple of years now with just this one problem that just happens to be related to the Milltronics controller, imagine that. My workstation has multiple CAD and CAM software running on Win 10 just fine, even better than they did on Win 7.
