I use an iMac 10.9.5 . Lightroom 5. Luanched Lightroom and folders all but two folders missing. Have read your tutorial on missing photos and followed the
instructions, but to no avail. This is a recurring problem. Tried File>Open most recent> /users /my name/ Relaunch. Didn't work this time. When I first turned on Lightroom I had a bouncing beach ball for a long time. Discovered I was off line and . Got back on line and discovered the folder panel only had two folders, there should be a lot.?
