I did a little testing, your fonts show up in ADE 1.8 preview, but not in 1.7.2. I renamed a couple of fonts to the same as in the epub and swapped them in and they work fine. Could it be that the file size of the fonts are too large for ADE (both over 600k each)?
 Yeah, definitely looks like something with the fonts not the css, the css file is loading (if there was something broken ADE wouldn't load any formating at all). It's loading the fall-back font and not the embedded ones.
