Looks like, open the first swf in FFDec, then open a random part and edit and save, and save the swf makes the swf corrupt. I have no idea why this happens. But it would be gold if this can be fixed.

So you are only swapping the label names? It has no sense, you can call them as you want. When you swap them, the result will be the same, but ok, it should work. And in the first example the parameter was 80, but in the same message entry the pushbyte has parameter 88. In the original swf it is 80. I modified it to 88, saved the file, and it was working. Please try to repoduce with the latest nightly build.
I still get the same issue. If I open FFdec. Then open a random part and edit and save. Then save the swf, it gets corrupt. As you can see in the picture.
Please be more specific. What are your current settings? Is deobfuscation enabled. I did the following steps: - open original swl - open ui.brickoverlays.CoinProperties - changed the following text: "Coins to collect to open door"; to: "Coins to collect to open door2"; - save in ASM panel - save swf (in ribbon) then i opened the swf: "flashplayer_12_sa_debug.exe freegame.swf" There was no error message. And earlier i've modified Bl.isKeyJustPressed(80) to Bl.isKeyJustPressed(88) There was no error in this case, too. So i need your current configuration and the exact steps to reproduce. (not only "open a random" thing)

The problem is in privatenamespaces handling, I'll try to fix it...
It is fixed in the repository. We will release nightly build soon. This bug is critical I think, thank you very much for reporting.
