I'm not sure exactly where it's spelled wrong, English isn't my first language, please let me know if you have a minute! :)
Ah, no worries: under Echoes - Audio Super Kit v1.5\Echoes - Audio Super Kit\Soundtracks\last charpter (loop).mp3"last charpter (loop).mp3" should be "last chapter (loop).mp3"
Ohh. Thank you for pointing it out!
