Strange. The page works in the version of gecko I tried, but it doesnt work in IE6.
It seems to have to do with the swfobject.js. If I remove the script tag, the page comes back. Strange again. Your host seems to think the js file doesnt exist. Obviously it does, since it affects how things works. Maybe it's just forbidden to view it and they use stupid error messages.
