Was having some issues with a recent batch of fresh R3D files not having saved "looks" applied. It was suggested that upgrading to Ver 51 might help and it did, but there were some hangups with all R3D files opening. I then tried upgrading to the latest OSX, that seemed to fix the issues. But then late last night I was revisiting the last batch of R3D's we had shot, and once again they are not opening. Their icons appear in the browser and with their graded looks seemingly applied, but it's a no-go on opening them. Again, all my other R3D's open with no hitch.
