Now, I have managed to create an AM_Main.cfg file and put it into a hand-created ArsMagicka folder in my config files. However, it still doesn't work. HELP!

Try different versions of ars magica and see what happens. Also make sure you aren't using a 1.6 version. I installed it without issues.

Don't move generated files into a file you created yourself. Let it generate on its own.

I've installed versions 5.52.013, and 5.52.013 without a single issue. It seems your issue is you are trying to make your own configs, which will not work.
