Adsense not displaying in IE

My ads are not displaying in IE. It seems like the ad below the navigation bar is taking up space, but the ad in the right column has no presence? I can’t find the problem.

I am viewing the website in IE 8.

Here is the link:
Home

I have a separate CSS file for IE,


.wrap {
	background:#000000;
	position:relative;
	box-shadow: #666 0px 0px 15px;
	behavior: url(css/PIE.htc);
}
#whitebox {
	border-radius:20px;
	background:#FFF;
	padding: 0px 20px;
	position:relative;
	z-index:2;
	behavior: url(css/PIE.htc);
}
#greybox {
	border-radius:20px;
	background:#999;
	padding: 0px 20px;
	position:relative;
	z-index:2;
	behavior: url(css/PIE.htc);
}

/* Right Column */
#rightcol {
	float:right;
	width:150px; min-height:700px;
	text-align:center;
	padding:70px 0px 20px 0px;
}
/* Youtube */
#rightcol div.youtube p {padding:0px 7px; color:#000000}

/* text */
h1 {color:#707070; font-size: 2em; margin:15px 0; padding-top:15px}
h2 {color:#006699; font-size:1.3em; margin:12px 0}
h3 {color:#707070; font-size: 1.17em; margin:8px 0}

Any help is greatly appreciated!

The ads are showing for me in IE8. Have you page refreshed / cleared cache?

Thank you so much! I did that and it worked.

I changed the Adsense to have rounded corners and then I noticed that it didn’t show in IE. I switched it back to square corners and had the same problem, but now after clearing the cache, it works.

Is the adsense corner option unstable in IE?

I’m not familiar with it. What does it involve? CSS3 rounded corners don’t work in IE versions 8 and below—at least not without JavaScript help.

Here is a screenshot of the option:

Hmm, that doesn’t give away much. Perhaps they use something like JavaScript. I doubt they’d be using CSS3 at this stage.
