@font-face Paths Don’t Seem to be working properly

I had an issue like that in the past, and the solution was so easy that was impossible for me to see, my code was exactly as yours and I had to change it to it… hope you have the same luck.

 @font-face {
    font-family:'Fertigo_PRO-webfont';
       src:url('fonts/Fertigo_PRO-webfont.eot'); 
       src:url('fonts/Fertigo_PRO-webfont.eot?iefix') format('eot'), 
         url('fonts/Fertigo_PRO-webfont.woff') format('woff'), 
         url('fonts/Fertigo_PRO-webfont.ttf') format('truetype'), 
         url('fonts/Fertigo_PRO-webfont.svg#webfont') format('svg');
    font-weight: normal;
    font-style: normal;
 }
