I need help! I downloaded lightroom successful but when i click on the file its pops up "Unexpected error opening Catalog" and it gives me the options to try again (tried that about 1000000 times lol), Choose a different catalog, and exit. I would be so greatful for help!
I would suggest to please create a new catalog and then try with the new catalog.
Incase you get the same error with the new catalog, please uninstall and then reinstall Lightroom.
Please let us know if it helps.
