Either I'm suddenly doing something silly, or something has gone wrong.  I'm seeing the same problem with multiple aperture and DP processing.  I've attached the log file.  I place apertures in the normal way, all images are plate solved, but it's reporting no signal for centroid, which there clearly is! Any ideas?

Log.txt

In previous responses to this question, Karen responded, "Are the images properly calibrated? In other words, does the background happen to have negative values? If so, the centroid will not work. In that case, re-calibrate the images with appropriate bias, and/or darks, and/or flats."

There are some -ve Int Cnts values. However, AIJ is failing to process images it processed yesterday, making me think this is not the problem.

One poster reported solving the problem "I was able to resolve the problem by removing by ~/Library/Preferences/AIJ_Prefs.

This did not solve the problem.

Best regards,
