Google Font Not Showing Up In IE8

Question

Apparently the font "Arvo" is supposed to work fine in IE, but I can't get it to show up. This is my css:

body {
background: #000 url(../imgs/black_denim.png) repeat center top;
font-family: 'Arvo', Arvo, serif;
font-family: 17px;
-webkit-font-smoothing: antialiased;
}

Works fine in all other browsers, at http://www.johnshammas.com/new. Any ideas?
