I recently downloaded a .swf file of a game, but for some reason whenever I load it in any player it just displays a gray screen.

I've opened it in ******* SWF Quicker and looked through all the files, and it looks like all the actionscript and files/sounds etc that are needed to make it work, but for some reason it only displays a gray screen that ******* calls a "Dummy Layer".

I've looked through the actionscript in almost all of the objects, but I've been unable to find any reference to a dummy layer or anything like that.

What could be going on here?
