How to make FSOD public ? Need help.

Hello
i need help with making my fsod source public.
I tried doing it by dhesscoORI tutorial. ( https://www.mpgh.net/forum/showthread.php?t=1170834 )
but all i get when i try to open my .swf file in yogda is this error: # Error : Not a swf file (Invalid Header ?)
Any idea how can i fix that?
Or any other ways of making the source public?

It'd be easier to use an as3 client, please follow winters tut here. https://www.mpgh.net/forum/showthread.php?t=1163271

@Giuen You will need Rabcdasm to decompile the client in order to load it in Yogda..
