Keith,
Unfortunately the log doesn't have much information in it. Would you mind turning on logging and repeating the test?
Run Photo Mechanic Plus, go to the Help menu and choose "Edit Debug Settings..." and then set the checkbox "CATALOG_DEBUG_LOGGING", then click the "Close" button. Next restart Photo Mechanic Plus and repeat your test, then from the Help menu, choose "Reveal Support Data..." and post the zipped log here, please.
Thanks,
-Kirk
