Banners being blocked?

I’ve noticed when I’m testing CS Cart out on my home desktop, the banners do not show up. I see the white space, and when I hover over it, it’s clickable.

@ Work, it’s just a typical Dell with XP, and I’m using Chrome, and tested it on a older version of Firefox also which works.

Maybe an ad-blocker like Adblockplus or noscript?
