Forma DJR Display Font Missing

So I'm a guy that captions everything being said with the font "Forma DJR Display" - usually with the Bold or Bold-Italic versions. Over half of my project is already edited using this font, as well as several previous videos, so I'd like to continue using it for continuity's sake and not to have a change mid-video. I loaded up Adobe Premiere Pro today, opened the project, pulled up text, went to the font selector... and the font's gone. I have not opened this project since several days ago so no changes have been made to the project, and I haven't had this problem before. Not sure if it's just a glitch I can troubleshoot or not?
