I really don't enjoy calling tech-support. Often, I feel like the solution they suggest is something I should've thought of myself, and probably would have if it was not my equipment that was malfunctioning. This morning, I talked to Matt at American Printing House, and after going through a couple steps, he suggested I try uninstalling NVDA again, and then searching for anything it might have left behind. This was actually quite a bit. Once it was gone, I was able to reinstall, and braille came up near the end of the install process. I have been using it a lot more than I realized, so don't remember ever being quite so happy to see those dots pop-up.
