Installation Problem

[TheFallenMushroom]

Most likely you have a folder somewhere called Amnesia: The dark descent. There should be a file inside somewhere called redist (Or something similiar) and inside there should be a file called custom_stories. Most custom stories you just shove the map folder in there. If the file is like an installation custom story just add all files to your redist folder and run the .BAT file. (I think it is something like that for the version you have. I'm not 100% sure.)
