.otf weird problem only in safari

Hi!

I'm using a custom font(.otf) It works perfect in IE, firefox on PC and Mac but not in safari MAC. Can't figure it out!? Please help! This is the css:

html {
overflow-y: scroll;
text-decoration: none;}
a:link {
color: #000000;
}
a:visited {
color: #000000;
}
a:hover {
color: #FF0000;
}
a:active {
color: #000000;
}
.koppen {
font-size: 50px;
font-family: "Warnock Pro Light Display";
font-style: italic;
src: url("warnockpro-lightdisp.otf");
line-height: 60px;
text-decoration: none;
}
.koppen-middel {
font-size: 35px;
font-family: "Warnock Pro Light Display";
font-style: italic;
src: url("warnockpro-lightdisp.otf");
line-height: 60px;
text-decoration: none;
}
.koppen-klein {
font-family: "Warnock Pro Light Display";
font-size: 15px;
font-style: italic;
src: url("warnockpro-lightdisp.otf");
text-decoration: none;
}
.normale-tekst {
font-family: "Warnock Pro Light";
font-size: 14px;
font-style: normal;
line-height: 17px;
src: url("warnockpro-disp.otf");
text-decoration: none;
}
