Fonts generated with Font Squirrel do not display in IE 9

I have used the Fontsquirrel @fontface Generator to create the CSS for the three fonts I am using. The fonts are displaying properly in every browser including other versions of IE — but IE 9 is not displaying the fonts.

Here is the CSS:

    @font-face {
    font-family: "OswaldBold";
    src: url("../fonts/oswald-bold-webfont.eot");
    src: url("../fonts/oswald-bold-webfont.eot?#iefix") format("embedded-opentype"),
         url("../fonts/oswald-bold-webfont.woff") format("woff"),
         url("../fonts/oswald-bold-webfont.ttf") format("truetype"),
         url("../fonts/oswald-bold-webfont.svg#OswaldBold") format("svg");
    font-weight: normal;
    font-style: normal;
}

@font-face {
    font-family: "OswaldRegular";
    src: url("../fonts/oswald-regular-webfont.eot");
    src: url("../fonts/oswald-regular-webfont.eot?#iefix") format("embedded-opentype"),
         url("../fonts/oswald-regular-webfont.woff") format("woff"),
         url("../fonts/oswald-regular-webfont.ttf") format("truetype"),
         url("../fonts/oswald-regular-webfont.svg#OswaldRegular") format("svg");
    font-weight: normal;
    font-style: normal;
}

@font-face {
    font-family: "OswaldLight";
    src: url("../fonts/oswald-light-webfont.eot");
    src: url("../fonts/oswald-light-webfont.eot?#iefix") format("embedded-opentype"),
         url("../fonts/oswald-light-webfont.woff") format("woff"),
         url("../fonts/oswald-light-webfont.ttf") format("truetype"),
         url("../fonts/oswald-light-webfont.svg#OswaldLight") format("svg");
    font-weight: normal;
    font-style: normal;
}

…and here are the errors I am getting in the IE developer console:

CSS3111: @font-face encountered unknown error.
oswald-light-webfont.eot?#iefix

I haven't had any luck with the searches I've done, any insight would be much appreciated. Thank you in advance.
