Top Menu not displaying in IE only

I manage a site for a client at https://www.autoinjury.tv and we’re having an issue where the top menu bar does not display when viewed in IE. There is also a scrolling marquee just below the video that doesn’t display in IE either.

I really hate hate hate Internet Explorer, and feel it should be abolished from the planet. But while we still have to put up with it, can someone PLEASE help me figure out the code I need to correct this?

Thanks so much!
