Flash 6 swf into Flash 8

I am trying to get a gallery to work - the file www.maraconconstruction.com/completedprojects.swf works on its own when it is published as a Flash 6 File, however I programmed the main file @ www.maraconconstruction.com as a flash 8 file and cannot load the completed projects file into the main file. Is there a way around this?

I have a file called maraconGallery.as in the same directory and my .xml file is called maracongallery.xml.

Any help would be appreciated.
