I can't seem to be able to replicate the problem but i did see some errors in IE when loading the page.
I was receiving this error message when loading your page:
CSS3117: @font-face failed cross-origin request. Resource access is restricted.

IE has very strict rules on loading fonts and font permissions and i think that these may not be setup right. The headers may also not be being called in correctly and therefore may be causing an error on your side.
Have a quick read up on this error which i think is what the problem is: IE9 blocks download of cross-origin web font
