When I downloaded the file and opened the folder it contained common4_ja.pac files.

I've tried renaming one of them common4.pac and replacing the common4.pac, but there was no changes.

I've tried opening up a regular common4.pac to maybe add it to pm's but I don't know what goes where.

Please help. I'm using the project M 3.0 hackless version.
