Hello! I am having a bit of trouble with Lightroom. While using Ligthroom, my photo drive was accidentally disconnected and therefore caused Lightroom to crash. When I plugged my photo drive back into my computer, I received the pop-up box shown in the picture below. I now have a new “updated” catalog along with the old one. I don’t know exactly what this means or how to fix it. I would so appreciate any help! Thanks so much!
