Where can I get the font Cloister Black BT Regular and have it embedded in a PDF?

I had this font installed on my mac and never had issues with it - then my hard drive went and when the time came to print existing files (Award certificates) that I had on file it appears correct in AI but when I convert to a PDF it says something about not embedding due to licensing restrictions? I will purchase if necessary but I want to be sure when I purchase that it will work. When I checked the info on a font I downloaded for free it said it was embeddable but its not the case … PLEASE ADVISE as I'm on a deadline and can't get this resolved no matter what I try.I've not had this happen with any other fonts that Ive reinstalled only this one. Thank you in advance!
