I've got a UC300ETH and purchased a license for their software that I am trying to get running. I've been talking with CNC Drive and they have been really helpful, although we're still not sure what's causing the issue. The board connects to my laptop properly and the license file was installed exactly as directed. I've also uninstalled and reinstalled the latest version just to make sure. Has anyone else come across this issue and found a way to fix it?
