MAKEA  Photomechanic continually malfunctions by randomly deleting my photos if I do any file management (batch rename, copy, ingest).

I no longer use the ingest feature as it sometimes works sometimes. It actually fails to copy whole sections of photos when it malfunctions, deleting the uncopied photos.

When batch renaming, it sometimes decides to do only half, leaving the directory scatterred with files named ʻTEMPxxxxxxʻ

None of the updates have cured my problems. As for the poster that suggested that this erractic behavior is the cause of a pirated serial number, I am running a purchased licensed copy.
