I received the Acrobat disk today, and it still didn't work. So I called them, and luck was suddenly on my side because I got The Lone Magical Dude Who Actually Knows What's Going On. He was rather peculiar, of course, but he sure fixed the problem.
The thing is, this is all sort of deja-vu for me, because I have memories of people in the art department having similar problems and fixing them in a similar way. I don't remember enough for it to actually be helpful, I just remember enough to go, "Oh, RIGHT!" when the solution is offered.
