Lightroom cant open some of my older DNG files, it marks the images as missing(the issue are with the complete folders, not some images within a folder), when I choose to find the files the folder seems empty, but when I look in the folder through explorer the files are there. I can open them in photoshop?! I use Lightroom and photoshop CC, and win10. The camera used was a canon 400d, and the images was converted to DNG while importing with lightroom. The files are from 2008.
