WebPlus X7: Problem of recognition of font without the 'www'

Why when I place to a text a different font, for example the font: 'Franklin Gothic Medium Cond', when I visualise it in my place with the "www' (http://www.xxxxxx.com) sees well, but when I look my place without the 'www' (http://xxxxxx.com), does not recognise the font: Franklin Gothic Medium Cond, and appears the one of 'Arial'.

And it remains everything badly the texts because it changes the font
Which solution give me?

I use this code
<style type="text/css">
@font-face {
font-family: Franklin Gothic Medium Cond;
src: url(http://www.xxxxxxxxxx.com/xxxxxxx/FRAMDCN.woff) format("truetype");}
</style>
