A final update... it works. Of course you knew that, but I was convinced otherwise.
One Internet search result for "Emacs No Match" linked to a subtopic of Completion in the Emacs manual. So I read more about Completion and found that pressing "?" displays a list of all possible choices.
So I pressed "?" after C-c C-w and saw
Tasks
Tasks (HR.org)
One quick forehead slap later, I entered Tasks ( TAB. I got the desired completion of Tasks (HR.org), pressed RET, and viola! It worked.
So this was classic error 18 because I was expecting to refile to ~/HR.org Tasks -- file name then heading.
Is the heading (file name) completion syntax explained anywhere in the documentation? If so, I missed it big time. LOL
I'm SO glad I got through this. Now I can get back to work.

I did try that. Same results.
I'm halfway through extensive testing, which includes two different fresh installations of Emacs on two different computers (both, regrettably, running Win 7). I'll try adding MELPA, too to see if that helps. If any other Windows users use org-refile (especially without MELPA or helm), please respond.
