Okay, I'm not sure what the problem is but here's what I'm finding...
Your .nef files will not open using Adobe Bridge, Adobe Camera Raw or Photoshop CC. They WILL open using IRFanview, a free image editing app I use a lot.
This has me stumped. The photos look fine in IRFanview but nothing else I have on my work computer will open them. The only thing I can think of is that the file headers are corrupt... But in all honesty, this is getting over my head. I don't really know what the problem is.
EDIT...
The only thing I can think of to try would be using different memory cards. I'm grasping at straws here but maybe the cards are corrupting the files somehow. I really don't know and in all honesty that suggestion is nothing more than a shot in the dark...
