BuddyPress Social not visible with IE browsers

I am using BP Social Theme for the website

http://svn.amebylon.net/

The website is not visible with IE browsers, but works with most others (I checked this on http://browsershots.org )

When I validate the website at

http://validator.w3.org

I get numerous errors that seem to be associated with how the menus are generated (list of errors included further below).

I am using WP 3.3.2, BP 1.5.5, Social Theme 1.3.5.

I tried turning off all plugins and the website is still not visible with IE browsers.

Any suggestions on how to avoid below errors and get the site working in IE browsers?

Thanks,

David
