Cannot import photos in Lightroom

[AC00513]

I'm trying to import a new folder in Lightroom and when I select the folder and press import, it comes up with a message "importing files", but nothing happens. I've signed out/in, unistalled the app and restarted it a couple of times and it's still not working. I think this is because of the latest update. 

Also, all my previous collections and imports have disappeared.

The first thing that you should try is to switch off the GPU support from the Lightroom preferences and check if that helps to fix the issue.

Go to Lightroom > Preferences > Performance tab > Uncheck "Use Graphics Processor" > Restart Lightroom.

If Lightroom doesn't start correctly the please see "Solution 2" in the document behind the second link.

Another step is to try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help we need more informations about your environment.

Which operating system do you use?

Which version of Lightroom do you use?

Please post the exact version and not only phrases as "recent", "latest" and so on.

Is that the previous catalog? Not a new one.
