Jquery Easing Slider not working in IE9

This is a weird one and I need help wrapping my head around a possible solution.

Please visit nsdstudio.com in IE 9 and see that the slider doesn't load in any i开发者_如何学Cmages. It should show just a preloader. Any other browser shows the images.

Now go to woothemes.com in the same tab and let the site load up. Now go back to nsdstudio.com and the see that the loader is working!

Anyone have any ideas to how or why this is happening?

Set isPreloaded:false in template/lib/lofslider/lofslider.js (about line 97)

Use these files in same sequence, I tested with IE 9, Slider is working fine

jquery.ui.all.css
jquery-1.7.1.min.js
slider.css
jquery-ui-1.8.17.custom.min.js
slide.js
