Some fonts are not compatible with Blitz. Almost the half of the fonts installed on my PC doesn't work with LoadFont. It depends on what type of font, I think. "Arial" does work for instance. I'm sure doing a search on this might clear that up.
If you're really determined to use that particular font, use Juicyfonts. It converts any font into a bitmap font.
