BRASSINGTON LANE FONT

Has anyone had experience installing any of these fonts? They come with very simple instructions that I feel are rather idiot-proof, yet I can't seem to get them to work. Basically, I delete the old fonts and pick the new ones out of their respective folders, and install (making sure to install, not just dropping them in) the fonts. And that should be it...or should it? Any help or experience would be appreciated, thanks.
