Hi,
Thanks! I kept fiddling, and finally did get those installed. I kept fiddling-- and I'm note entirely sure what I did. But in some cases, I did visit the download area, found current versions and put those in the directory. (I figured since I can always revert to the old, it was better to fiddle than not.)
My only problem now is the combined question doesn't work. Part of the question entries display in the question bank, but the full questions don't. They just display a blank when I attempt to view-- also quizzes that contain them don't display. I'm going to be trying to figure that out.
