Get rid of the random image tag at the start, this won't help if your first line of code in the body is invalid
Code:
<img /><!--[if gte IE 5]><style>#container {margin-left: -351px;}</style><![endif]--><!-- Master Container: Centered and 700px wide --><div id="container"><!-- The topmost bar --><div id="topbar"> </div>
Your first part is a closed image tag, there is no open tag I can see so it's confussing IE maybe?
