Please note that official support for this menu version has now ceased. There are still plenty of users, though, and the forum is still running. Some of our long-time users may be able to help you out.
The right horizontal menu works fine, but the combined frames menu doesn't. My browser reports about a error: code 0 / access forbidden to the left navigation frame with the other half of the menu.
If you load content from another site and try to insert your own code (as is the case with the menu) the browser will complain. It's a security thing. You could always try using an IFrame and see if that helps.
