I can't figure out how to load the custom story

[joshissac]

Assume the redist folder from the archive is D:\Program Files (x86)\Steam\steamapps\common\amnesia the dark descent\

lets assume I really suck at assuming things

it's now D:\Program Files (x86)\Steam\steamapps\common\amnesia the dark descent\redist\custom_stories\Nintendo Castle Horror up to where the maps folder is located, but nothings changed at all, still won't add the custom story to the game
