Respond.js not working, error in console

Hi

I installed this plugin on a newly created website. but under IE8, nothing happens.

In the console i got the following error:

Line: 6
Error: Could not complete the operation due to error 80070005.

my queries all look like this:

@media screen and (min-width: 480px) {

	#mainDiv {
		width: 95%;
	}

	#footerNav>div {
		float: left;
	}
		#footerNav li {
			width: 100%;
		}
}/*/mediaquery*/

hope someone can help?

Simon
