Problems with preloader code

1

In the following code I set my preloader to play an swf. If I test the preloader inside or outside the flash author environment it plays the swf. If I change the swf to a new file name and resave the flash file with a new name it won’t play the new swf. I can’t figure out whats going on. I am using FlashMX 2004 Prof.


/* First thing to do is set the stage size of 
   this movie at the same size as your 
   "to be loaded" movie, and re-position the display
   elements to your liking.
   Also set the same framerate as your movie.
   Then replace "YOUR.swf" in 2 of the lines below, 
   with the name of your movie.
   Last, make sure your present movie is cleared 
   of any preloader.
