Internet Explorer issues with Theme

Hi, I downloaded the Fluid Solution Theme for wordpress and changed around some code. The theme didn’t have widget integration so I added the Google Adsense code myself to its file ‘left.php’ and ‘right.php’ which are the sidebar php files.

The site shows up perfect in Firefox and Safari and I even tested it in Internet Explorer 5 on my mac and it works. But for some reason ie7 seems to only show 1 post and the start of the 2nd post and nothing else. It doesn’t show posts after the 2nd title and doesn’t display the side bars. Take a look https://www.manvsmedia.com

What could be the problem?
