Could you please let me know the exact issue that you are facing with Lightroom, so that I can try and help you.
When I try to download my catalog of approximately 30,000 images with the pop up screen that appears when I start Lightroom, it stops at 8.3% progress in step 1 of 3 in “preparing catalog”. I have used the repair catalog feature and it finds no errors. The first time I tried the download it was successful with about 300 images but will not budge from that number on successive attempts. I have Windows 10.
Thank you for the update.
I am sending you a Private Message , please check and reply.
Upgraded the Catalog, able to see the images in Lightroom.
