For some reason IE9 doesn't appear to be loading my css file at: www.languageforlearning.co.uk
its loading fine in FF, Safari and Chrome, so I can rule out a broken link. The type attribute is set to "text/css", so I can rule out some kind of MIME issue.
Unfortunately I don't have a copy of IE9 at the moment, which is making things a little trickier, since all I can really to do get a look at the page is use an online screenshot generator.
Any help would be much appreciated.
