I just upgraded from the mark iii to iv and this is the first set of images I've tried loading into lightroom with the new camera. I have updated my creative cloud suite so both lightroom and camera raw are the latest that I can get but when I load.. LR says it can not generate a preview for the images and that there are no images to load from the card.
I know images are on there and can't seem to resolve the issues. Any other suggestions?
If you mean Canon EOS-5D Mark IV, you need the latest version of LR - CC 2015.7.
You can update using Help > Updates, if that fails you can download the 2015.7 update from here:
