all you need to do is put the folder it comes with in the mods folder and type /loadmod enderman.race, or if you have it in a folder it would be something like /loadmod (folder name)/enderman.race
it says unexpected character something something because the first one you said didn't work so i put the file name and I'm new to this .
sorry, I'm not quite sure what is wrong you might want to just join the NTT discord and ask for support there
