Thank you for your input. It appears to be the answer.
I can not modify the file in Capture One Pro either.
I have right clicked on the file in View NX2 and the It allows me to protect the file with the key symbol, but I can not unprotect it.
Do you know of a way to unprotect these files so the can be further modified using another photo modifying system?
