As of 2 days ago, all of a sudden, my raw cr2 files from my SD Card (from Canon 6D) can't be read when importing. The Photos show up, but Error Message appears when I hit Import. I can import via Apple Aperture, Adobe Bridge/Photoshop, but i've worked for hours trying to understand what is wrong with LR. I uninstalled LR5, and installed LR CC that came with my Photoshop. I've run system checks and my SD Card is good. All my Adobe Software is up to date. I'm completely stumped, and this isn't just a Hobby. I've a photo shoot tomorrow, and I rely heavily on Lightroom. Any help is greatly appreciated.
