Xml external swf's trouble

I hope somebody can help me with a problem i am having…

I have a .swf(main.swf) which contains 2 moveclips. (content_mc & menu_mc)
Each movie clip loads an swf file.

The swf i am tryin to load into content_mc is ‘audio.swf’ which contains individual buttons to play individual tracks via xml date.

audio.swf works fine when i test it, but when i play the ‘audio.swf’ within ‘main.swf’ in the content_mc, i am gettin an error saying 'Error opening url http://…/undefined

My xml
