AS3.0 Loader problem

Ok, so I’ve got a swf file that loads another swf file with fonts at runtime, when testing in the Flash IDE, the fonts load fine, but when tested in a browser localy and on my server, the load fails and I get a debug message
“Error #2044: IOErrorEvent : text=Error #2035: L’URL est introuvable.”
basicaly it can’t find the url…
I’ve tried everything I could think of, if anyone can provide insight I’d be grateful =)
