Topic: loadmovie stuck to "loading navigation"

i'm loading the viewer.swf into a movie clip named "prt" using the following script

_root.xmlDataPath = "gallery_jamar.xml";
_root.preloaderColor = "0xffffff";


this one works in html so there is no problem with the location of the images/thumbs

the viewer.swf is loaded in my main swf but it freezes on "loading navigation"

anyone has an idea?
