I just migrated my 4.39TB library to Lightroom CC, and upon opening it and trying to add some new photos, I watched all my albums in the left sidebar just disappear. Where did they go, why did they go, and can I get them back? My library is huge and the albums were pretty important to me. Additionally, I seem to be unable to add new albums. When I try to create an album or folder I get the dialog box, type in the name, hit enter, but then nothing appears in the Albums sidebar.
