FATAL ERROR: Could not load world file...

[Vanillacrazycake]

Back when Amnesia first came out, I finished the game and attempted to make my own custom stories. After a few failed attempts to "set up a dev. environment", I uninstalled then reinstalled the game to reset the change in code I did to get the dev stuff working...



Every time I attempt to load the game it crashes instantly, with this error showing up. I've never had any problem like this before, and Amnesia worked perfectly the last time I played it. I've tried everything and there's no way around it so far, any ideas would be greatly appreciated!
