Unfortunately it didn't work. After I saved it as a zip and dragged it into C3, it said it wasn't a valid .c3p file. I even Tried changing the extension to .c3p
Odd, this should work unless something changed with that since then. Or you zipped the folder you extracted into (if you open the zip there shouldn't be an extra subfolder, just the project files) happened to me too before.
Either way, r161 now crashes on startup with no error message. Same on laptop.
