I've come upon a rather perplexing problem while editing a .CFG file in Notepad++ (for Step 8 of this). Previously, I have had no problem editing the configuration files for Amnesia or with saving my changes. To fix this problem, I have tried closing all other open windows, restarting Notepad++, and restarting my computer. Unfortunately, none of this has worked.
Please, if you have the answer, try to put it in fairly English-based terms (like the tutorial that I placed a link to). I have a rather basic grasp of how the program works and how to use computers, but I certainly would not be capable of creating a program from scratch or making any major changes to my computer. Thank you very much for dealing with my lack of knowledge!
