I have been sent a .PMX file to import into PM to add some relevant fields for Getty requirements. When loading it into PM, however, it seems like a blank file. The first image is a screenshot of the import box. I have loaded the .PMX file into TextWrangler and there are (what I guess) fields which can be added within PM. I've added a screenshot of the TextWrangler file to show that it isn't blank.
I know the PM file isn't updated as I can't see the fields that Getty require (Personality is one) inside the IPTC fields.
Can anyone explain how I can add the newer PMX file into PM please?
I'm running Mac Yosemite 10.10.5 and Photomechanic 4.6.9, 8GB RAM.
I am grateful,
