This is common with effect for free site users, that are trying to use frames. Your pages are not showing because your frames page does not have a section. A section would contain the tag that the ad banner insertion software is looking for. Adding one would allow your frames to display.
But, even if you did add a section to your pages, it wouldn't help much. Each of your frames contains a web page, that also has a tag, causing banners and popups in each frame. Some web hosts allow users to suppress banners, on frames based sites. However, Bravenet is not one of them. Unless you upgrade to paid hosting, you will need to convert your pages so that they don't require frames.
