I've done the following a hundred times or more: I edit and partially caption my RAW files in PM 4.6.8. Then I process them with DxO into a new folder. So for example I get a 2mb DxOjpg. Then I put them back into PM and crop and finish captioning (each file a different caption). Then I click 'save as' direct from the PM magnified window with the 'crop' box clicked and save into another folder. I've done this so many times I can't remember, always successfully. Tonight I can't open the files in the end folder 'unsupported format variant' DxO JPG etc. The original jpegs are opening OK. What am I doing wrong? I don't always add to the caption in stationery pad, tonight I am. Is that the problem?
