I've had a quick look at the code on the page and all the advert is is an animated gif in a table with a link to your website. This is nothing to do with popups and as such will not be in the least affected by Pop Up Blockers. I use Windows XP SP2, which blocks popups, and I can see your ad fine.
And the radio you supplied to me is still working fine as well. /forums/images/graemlins/laugh.gif
