Google Adsense not showing in Thickbox!!

Its weird. the adsense appears in Chrome. but not in Mozilla or IE. example [login to view URL] as soon as you go in the site a thickbox will popup. And as you'll see, the ads only show in the Chrome browser and not in IE or Firefox. The content inside the thickbox can be seen here: [login to view URL] I've been trying to fix it for a couple days now and still nothing. I need a freelancer to fix this problem so that the ads can show on every browser. The faster this gets fixed the better. note: the thickbox is set up to show only once for every user. For the thickbox to show again you must close and reopen the browser.
