I have looked all over the web for this answer, but have failed to find it. I have a new Nikon D7100. I took photos with it using the lossless compressed RAW format. I transferred the files on my PC using Nikon Transfer. However, Lightroom 5.5. (on the same PC) will not import the files from their folder--like it does for JPEG files. Lightroom says my version is up-to-date. Help!
