I moved a bunch of photos to an external hard drive. After doing so I tried opening LR. I received a message telling me connection with my catalog was lost. Not knowing my catalog would be gone for good I click new catalog. Now I can't find my old original catalog. Please help. Can it be located and reconnected? Or is it gone forever?
Assuming that your old catalog is still where it was (i.e. you didn't move that as well)
1. Open Lightroom
2. File Menu
3. Open recent
and you should see the old catalog listed there
