Problem with "dev" mode

[varto]

Well i got the map to load properly with no problems without dev mode(used back up cfg files). But when i use my edited cfg files and load amnesia, the game starts up but then gives an error saying "failed to load config!" My map files are in the "Custom_story" directory and folder structure, it's pretty much like the way everyone else is doing. Please help me out here i don't know whats going wrong here!
