    "Preview unavailable" for NEF files in Lightroom 6


      Hi my computer - Acer Aspire with Windows 10 has stopped reading my NEF files. A short while ago there was no issue - I transferred the NEF files and imported them without issue. Suddenly that changed. Now, for all my NEF files I get a "Preview unavailable" message. I have set the camera to shoot RAW and JPEG and Lightroom only recognises and imports the JPEGS. I have seen in these forums similar queries have not been answered. Is this something to do with an automatic Windows 10 update? Right now my Lightroom is pretty much useless. Help!
