I remember in art school they said, "only paint if you have to". I have to.
I fiddled around with the camera, the tripod and so on, and though I still ended up with a bit of distortion (the bottoms of the paintings keep being narrower than the tops, so I end up cutting off a tiny bit of the sides at the tops), I have mostly learned the new method.
I thought I had ruined the quick release camera mount on the tripod, then later saw that I had the mount on backwards on the camera. Fixed that, and bingo! it snapped right in.
Now I can ship this baby to a gallery!
