Studio styling in IE is not looking so good!

Hey guys,

My site http://www(dot)marketingcompass(dot)co(dot)uk is build in wordpress, buddypress and using the studio theme and looks great, however using IE it’s terrible. The whole site looks mangled, the main text is white on a white background and worst of all I don’t know where it’s getting the styling from?! Could you take a look (might need to signup for a free account and get into the community part to see the worst of it in IE)
