Just purchased a new Nikon D750and shot a few pictures in RAW. On importing to Lightroom receive the message Below, The files are not recognized by the raw format support in Lightroom (55)
You missed to tell us which version of LR you are using.
You need at least 5.7 to have the D750 supported: https://helpx.adobe.com/creative-suite/kb/camera-raw-plug-supported-cameras.html
