When I right click an image and try to edit in one of the NIK modules, I get this error message:
Lightroom was unable to prepare the selected file at /Volumes/LaCie/Foto/2015/04/02/20150402-DSC02450.ARW for editing.
It will not be opened.
I have tried checing harddrive permissions, but haven found the problem. I have also deleted the hidden preferences file, but the problem persist. I can export images fine.
