Hi Suzanne -
It's loading for me now in IE8 but I cannot see the header or whatever is right above the shoes. I am getting little boxes with red X's - but that's better than the error message. It may just be me, because when you first posted I had the same problem and could see the headers, etc. in Firefox. (I do not have the most recent version of FF - fortunately!) It's late right now (everywhere but here) and I'm sure others will LYK if they could load and see everything on your site.
Sorry this is such a hastle for you. What I can see looks great!
