I can try to help you,
Click on you main folder. That holds the SRC folder. Then put the curser in the white area, and right click. Create the File text there. Then name it Path.yml, as you said.
If you did this correctly, then it should work.
If it didn't, you probably did it wrong, or miss understood me.
Or the line in the file, is broke it's self.
Meaning, you didn't set the 'Path' correctly.
Something like(Example):
Main: me.fireblast.Korra.abilities
This line would go in your path.yml, if it's setup that way. Hope this helps!
It's harder for me to explain, because I can't show you. So if you didn't understand.
I'm very sorry.
Maybe then someone better, can assist you.
Hope you figure it out!
