Problem with Internet Explorer

I’ve been trying to get to a couple of sights lately to get manuals and info. When I go to the WEB page instead of info, I get what I believe is a holder for info. It is a small box with a red x in it. I can’t get the box to open or display info. One site that this is happening on is the MTD products page for serial nmber location. I’m using Internet Explorer 6.0.28.

Thanks..
Bill
