Site not updated since upgrade to 2.3.3

I upgraded to Wordpress 2.3.3 on the 11th of March, and since then the site has stayed the same. If I use Firefox on my computer it has been updated and I can see new posts but if I use IE then my site loads up exactly like it did before I updated. Since the update I have changed my sidebar around a bit and on IE I can still see the site how it was when I updated.

At first I cleared my cookies but that is not the problem. I have asked a couple of friends and they can still see the old version of the site.

It is either a problem with the update or I may have done something when I changed the position of my adsense ads, but it is likely to be with the update.

Anyone know what's happened?

Note: This only happens on the main page, www.filmonic.com

 

have you cleared cache and temp files?

 

In the browser or wordpress?

 

in the browser, you only mentioned that you cleared cookies in original post.

 

Ah. Deleted temporary files. All works well. Thanks
