Failed to load config file - A stubborn one.

[Tottel]

So, I've been doing the "Setting up Development Environment" from the wiki. My map works fine when setting it up as a custom story, so technically I am good to go and develop things.
It's just that I want it to work the way it should. Especially since I plan on constantly testing small things, so it would be handy to have the debug version opening directly.

I did everything according to the wiki. In my 'maps' folder there's a new map names 'test', including two files: 'test.map' and 'test.hps'.

Now, when I launch the game, I get a black screen, go back to desktop and receive that error message: "Failed to load config file". I checked the log in the save folder, and it includes no errors at all! Speaking of annoying..

Any ideas what might be causing this?
