IE Not loading my images from CSS

My site appears fine in FF & Ch开发者_开发技巧rome, but load it in Ie (tested in 7 & 8) and none of the background images load.

The CSS appears to load properly, just the images are not showing up. Any ideas?

You are using multiple background images, which are not supported by IE up to 8.

background: url('../images/main-background.png') no-repeat, 
            url('../images/main-background-repeat.png') repeat-y;
