I updated last week. After trying to export a video from LR it said I had not enough room (New Mac Book Pro since Oct 2015) on the hard drive said I needed to free up 20MG of space, when I clicked ok all of my 2016 files in LR are gone. My images for 2015 are there, the few I had but those edits are also gone. I just finished editing a wedding so 625 edits are GONE! Anyone know what happened? Are they in some folder somewhere???
