Operation Aborted Error in IE

[cgermain]

I have used CSS to build my web site. It works in Firefox, but I get the following error upon page load in IE:

"Internet Explorer cannot open the Internet site http://www.wanttobevagabond.com
Operation Aborted"

I then press Ok on the error message and it defaults to a cannot display this page page. This does not happen in Firefox. I feel like it might be a CSS issue, but I can't find the bug. I also lcall a random banner image using javascript and call the css menu into the nav bar. Any help in allowing this page to load correctly in IE would be much appreciated. Thanks
