Right now I'm trying desperately to get @font-face to work in my website. This is the code I am using right now.

@font-face {  
font-family: romeral;  
src: url(fonts/romeral.otf ) format("opentype");  
}

And then....

h1 {
font-size:2.5em;
font-family:romeral;
}

I am using the font Romeral. Here's a link to it: http://www.smashingmagazine.com/2007/02/06/freefont-of-the-week-romeral/

For some reason it just won't work. It won't render the font on the page. I've tried using other fonts like Ripe, and they work. I've made sure I don't have any spelling errors. What I'm wondering is if there is a restriction that some fonts use to stop people from using their fonts with @font-face. Or maybe I've made an obvious mistake in my code.

Thanks in advance.
