After copying the 50 mb file, I enter the game from the save location but it gives an error.Make sure to download the correct one : LINK
Everyone seem to love getting bugseven though posted in red on the mod page says not to use on newer game versions.
Glad you got through though and when it is updated you just have to download the patch/mod and not the entire game.
I recommended always backing up the data folder in the game directory. So if any problem ever arises, you can easily fix instead of having to download the entire game.
