Strange Problem with @font-face in FireFox

I just finished a website using an @font-face kit. Everything looks fine in Safari, Chrome, Internet Explorer, but in FireFox, some of the letters are not appearing correctly.

Example (http://buddha.fuelmultimedia.ca/atmosphere/)

The title appears to be Atmosphere in every other browser, but not in FireFox. Does anyone know what would cause this?

To me it appears the WOFF font wasn’t converted properly as it’s actually missing letter completely from what i can see. Also i noticed that the font your using is a premium one, you should consider using a .htaccess file to prevent un-wanted direct access to the font files as by default browsers send the header type as a downloadable file.
