FATAL ERROR: Could not load world file 'maps/main/50>'

[jens]

Here is a default folder with the settings and user profile created from starting the game the first time. Try that and see if that helps, if so then try to make a new profile and use that.

So unpack this Pig folder and move it to My Documents/Amnesia/ and replace (or first delete) the whole Pig folder there is already.
