I just got done shooting and am now trying to import my photos into Lightroom 5.5. Lightroom pulls up the previews from the session and selects all but when I try to import them I get an error that says Lightroom can't read my files.
The only thing different I have done is I loaded some images from my Canon 7D a few days ago and now trying to load from my Canon 5D3. I reformatted my card before the shoot.
The destination folder — the folder you want to copy the photos into — does not have WRITE permission. Change the permissions on that exact folder.
