As it says
here,
All three versions are in this post, but choose ONLY ONE to install. Please note this is not supported and will not be updated. It's compatible up to and including the M&G Stuff Pack.
M&G is considered an EP, and you have it, so it should be "safe" to download the version you pick. They're the same, but shows up slightly different ingame.
