I opened up LR 5 today and found that NONE of my images show up as thumbnails, filmstrip, in develop module, import or anywhere else. In develop module, all develop settings are there. The only thing missing is the image itself. I cannot see ANY of my images even though they are physically there on the HD. If I select an image (or image placeholder) and select "edit in PS", then PS opens and I see the full image for editing. I just don't see any of my images while in LR. I've rebooted my comp, did a "repair" on the LR installation and even a re-install of LR5. NOTHING works. I need help!!!
