I had the same issue too but figured it out.

For me, Notebad automatically put a ".txt" at the end of the file AND I didnt' readily see it because my File Explorer was set to not see extensions. So even though I saw the "sw.unl" file, it was really "sw.unl.txt" and it would not work.

After messing with File Explorer settings to "see file extensions", I was able to delete the ".txt" and it worked.
