Hello Team, I have a macbook with Lightroom on it and a desktop running Vista with Lightroom as well. I had my desktop with all my pictures on it, rated, sorted, etc. Then got a laptop traveled around got new pictures, rate, keyworded, etc. Now that my laptop and desktop are finally back together, I transfered over all my pictures from the laptop to the desktop. They are now unsorted and untagged. So I transfered over the Lightroom 2 Catalog from my Laptop and opened it up on my Desktop. When doing this it looks just as it did on my laptop, but still doesn't acknowledge the older photos from before. My Question: How do I merge two lightrooms with two different Catalogs from two different computers, while keeping all of the ratings and keywords. Thanks!
