the prior library catalog I was using that had been named Lightroom Catalog-3-v11 was upgraded with the new April softwared update to catalog v11, and all (ALL!) the files i've added for well over a year are not showing.
I want them back! How can I get the photos added into this? Very time consuming to have to reupload, plus I'd lose all my selections, tags, etc, etc.
I've relaunched the old catalog as well as relaunched the new V11, and same result. Pretty sure they're not "gone", but regardless I cannot find them. Please help!
Accidentally, the wrong catalog was updated. You need to find the catalog you want. First, use the menu command File->Open Recent and select each catalog shown there until you find the catalog you want. If that doesn't work, use your operating system's search feature to find all files whose name ends with .LRCAT and open each one (by double-clicking on it) until you find the catalog you want.
