After downloading and unziping the Flux font file, I have tried installing through the font folder as well as through the font installer associated with the font file. The font loads and shows as installed, however when trying to use the font, the font shows as only boxes (doesn't work). I have tried closing the application as well as restarting my computer, but font still won't work. Need help!...

Which Flux?

Flux Architect. Initially, all the fonts showed in the viewer, now the regular does not show at all in the viewer. None load.
