Custom Font STILL wont work in IE

Question

The webpage where I'm trying to get the custom font "Duke-Fill" to display is http://www.hamlinforcongress.com/helpout.php

I'm using:

@font-face {
font-family: 'header_font';
src: url('Duke-Fill.eot?#iefix') format('embedded-opentype'), 
     url('Duke-Fill.woff') format('woff'), 
     url('Duke-Fill.ttf')  format('truetype'),
     url('Duke-Fill.svg#svgFontName') format('svg');
}
.header_font{
font-family: header_font;
}

I've tried every other suggestion I can find on the Internet, but nothing can make the custom font display in Internet Explorer. It works perfectly in every other conceivable browser, but not IE (surprise surprise). Help?

Answer 1

@font-face {
    font-family: 'NimbusSanConD-Lig';
    src: url('fonts/228BFB_1_0.eot');
    src: url('fonts/228BFB_1_0.eot?#iefix') format('embedded-opentype'),
         url('fonts/228BFB_0_0.woff') format('woff'),
         url('fonts/228BFB_0_0.ttf') format('truetype');
    font-weight: normal;
    font-style: normal;
}

This code works in IE. It was generated using Font Squirrel
