Sounds like LR may have created a new empty catalog during the install and selected that one as your current catalog.
Go to the menu /file/open-recent/ and see if your old catalog is listed there.
How do I change what is under open recent? I saw someone do it on youtube
but cant seem to find it.
Or is that even possible?
You can't change what is under Open Recent.
You select each catalog listed there to see if one of them is the one with all your work.
I GOT IT! because of you! Can't thank you enough!!!!!
