I am having trouble importing my photos. I am doing at as usually do, I insert the memory card on my Mac and then I hit import photos. Once those are imported I am usually able to start developing them, however, this time when I go to edit them, it displays a sign saying "file not found". I have encountered this before when I have moved the photos from their original location and then an interrogation sign shows in the folder. This time is different though because it happens right after import and I know for a fact that I have not modified the location of the folder. I have also tried to right click and hit update folder location and that does not work. I have also tried importing the photos to my computer first on a folder, and then importing them from there to lightroom, but that is not working either. Please help me. I really need to edit these. Thank you so much!
