Which images did you place in the bodies folder? The zip contains the folders in the structure they need to be, IE there is a bodies folder, an exposed folder, etc. Those all need to go on the same level, as in those folders don't belong inside the bodies folder, the bodies images need to be in the bodies folder, then next to it you need to have the exposed images in the exposed folder, etc. Make sure that you have one of each of those folders, and that there are only images inside them, and all of those folders are in the "Strive for Power 2" directory.
Edit: And to be clear, I mean the "Strive for Power 2" directory that is apparently somewhere under appdata if you are running windows, or on Linux and probably macos it is in ~/.local.
