Lightroom version: CC 2015.5.1 [ 1073342 ] Windows 8. After updating , CC,LR and PS on 5/22/2016. The following happened, after importing no folders show up after 5/22 in navigator. When i close reopen LR the pictures I imported are no longer there Attempt to re import only greys out the pictures, meaning they show as being imported. When I do a search for a file , the search comes up blank. I will also add that I have LR convert from NEF to DNG. This has happened to another person that I converse with. Under Destination date format shows 2016/2016/05/xx I change this back to 2016/05/xx but it defaults back to 2016/2016. All this happened after the updates . Any Ideas ?
Reset the preferences for Lightroom back to default, then try it.
Press the shift + option keys immediately after you restart Lightroom, and select Reset Preferences from the resulting dialog box.
