Missing fonts in Illustrator on Windows

I've spent a while creating my product labels, and the main font is Bebas Neue Regular. All of the labels are saved as an AI file and i print directly from AI. But a couple of days back that particular font is missing from every document? Its in the thumb nail, and if i open the doc in PS it prints ok. Theres not even palce holders or a substitute font in AI If i check the fonts, it shows up but it is blank on the right where it has the favourite star etc. Checking in the fonts file in windows, it is still installed. Ive tried to restart AI. I've reinstalled AI, but no change. Im on a pc using Window 10, and AI is on CC Thank you
