Problem with external swf tutorial MX04

Hi all,

im working through but mine is not working :

its just loading the main swf, but not the “home” swf, and also the “home” swf is not playing correctly. i think its because in the sample files, they have used a blank keyframe in the actions layer… or so it appears, but in the tutoral i does not mention this so i just added the blank keyframe so that i was able to add actions… the fla are at:

any ideas guys? many thanks
