It's hard to say where the issue would be, then. I would just say double check to make sure there aren't any typos, that you've changed all the instances of the font's name, that you've made sure that the name of the font and the file extension are correct, and then maybe just try a different font to see if it could just be that IJ doesn't recognize the one you've linked.
Without seeing the ooding itself, the best I can offer is double check everything.
