SWF Decompiler does not find all the files

Has anyone ever encountered the same problem?

Im trying to decompile a certain swf game but decompiler simply shows / returns only few of the resources while there are many more.
There are no main game graphics or even game actionscript files inside. Just some preloader, start page graphics and advertisement scripts. Even when opening the converted .fla file itself.

I would like to find the main game actionscript files to help me understand the as3 language and game development more.

Im using the newest swf flash decompiler (full version), so software shouldnt be a problem.

Its a real tricky one, cant understand why.
