My custom font doesn't want to work in Internet Explorer

I'm trying to use the Green Pillow and Cotidiana fonts on a site I'm working on. I've loaded the .eot file using @font-face but it's still not working...

Really not sure what I've done wrong here:

@font-face {  
 font-family: "link_font";  
 src: url( "Greenpiloww.eot" ); /* IE */  
 src: local("GreenPillow"), url( "GREENPIL.otf" ) format("truetype"); /* non-IE */  
}  


@font-face {  
font-family: "twitter_font";  
 src: url( "Cotidiana.eot" ); /* IE */  
src: local("Cotidiana"), url( "Cotidiana.ttf" ) format("truetype"); /* non-IE */  
}
