Just got this. Win 10 pro, up to date. It got past detecting gaps, then ripped for a good couple of minutes, but crashed multiple times. Tried quitting/restarting CUEripper, found that it was still visible in TaskManager after quitting (new instance couldn't open disc drive). Win10 reboot fixed the problem.
