Uh, it sounds like you're doing everything right, but there are no bugs or anything around this so I'll just go through the details.

Firstly, are you using Windows?

Let's say dominions is in c:\games\dominions3

Find the folder c:\games\dominions3\mods (check the spelling - someone before had a folder called "mod" which didn't work).

Unpack all the stuff from the zip into that folder. So now there should be a file called "diversity_1_1.dm" in the mods folder. That's all you need in order to be able to select the mod from within dominions.

There should also be a folder called "diversity" full of sprites in the same place. You don't need the folder full of sprites in order to be able to select the mod, but when you actually try to use it the game will crash unless the sprites are in the right place.

Let us know how you get on.
