Help me!! custom story not working

Look at this post and add the bold line to the bottom of the resources.cfg file. You can find the resources.cfg file at the same place you installed Amnesia, and can open it with a text file.

If you have not already, I'd also consider updating your game, which you can do from here: http://www.frictionalgames.com/forum/thread-24334.html
