I think you have misunderstood our comments, the mod doesn't fail, it works, but when you open it only code comes out, what you would normally put for example:
add.coins. 200/ is example, the code does not exist as I put it
the mod works but without descriptions because the game doesn't find the MTL folder inside the mod text folder, just create one and copy your language inside it from for example the ENG folder, it won't pop the warning and it will load the text with its description etc.
to sum it up, if the game doesn't detect the folder for example ENG inside text in the mod folder it warns you, when you open the mod menu without the translation you will get the raw text which would be for example add.coins 200
