Thanks, Andrew Yes, I had a Time Machine backup, but I wanted to use the latest OS. I finally got it fixed, I think: I reinstalled the driver (which had no obvious effect--still missing profiles), but then I tried re-installing a am1x file. I had to overwrite the file that was already there, but not visible--and with that, all the other profiles reappeared. The ones I was concerned about were only the ones that came with the printer---it's weird that reinstalling the driver didn't bring them with it. Anyhow, it seems OK now. Thanks again!
