Just started with Lightroom CC 2015 but am highly experienced Photoshop user.
Just tried using LR to create a 1st catalog of all my photos from all my hard drives. Seemed to work great and showed about 2,800 thumbnails - but now everything is empty and only shows grayed out????
I must have missed something......thanks for any help!
You have lots of folders with question marks, which means they are disconnected or have been moved outside of Lightroom e.g. using Windows Explorer.
What happens if you click on the folder which is not missing – the one with 197 items? Can you see the thumbnails?
