SimpleAdditions doesn't generate C++ output file

[MassMessage]

I downloaded the release version I'm trying to use SimpleAdditions like this:

SimpleAdditions myfile.il

But it output the number 4 on the screen and doesn't generate the C++ output file. Is this a error code? if so, where can I get more information what does it means? I'd like a working example how to use the application. If matters, the MSIL I'm trying to compile is one decompiled from a C# executable http://pastebin.com/uh82RUbV

Thanks in advance
