[mystique] Logo not loading in IE8

Hi,

My website is http://ablemagazine.co.uk – Webpage loads fine in Firefox/Chrome etc, but it’s a bit messed up in IE

The main problem is the logo isn’t displaying (top-left)

other minor problems:

The images in ‘featured posts’ aren’t loading
the twitter button sits underneath the menu bar
one of my ads isn’t loading (under the first post – not sure if this one is a mystique problem)

Thanks
