Please uninstall the current version of Lightroom from Control Panel.
And please install LR 6 from the following link : Download Photoshop Lightroom
Please let us know if it helps.
Nope, did not change anything.
Any other solutions?
Could you please launch Lightroom by holding the Ctrl, Alt and Shift Key .
You should get a window to delete the preferences of Lightroom.
Please delete the preferences and then see if you are able to see the numbers in the sliders.
Thanks for your fast responses, really appreciate it
I get that window, but I can only see "general, link, compatibility, safety and details" in which I topic can I delete it?
Please right click on the Start Icon on the bottom left and then click on Run .
In the Run window please type : %appdata% and hit enter, go to the Adobe Folder, then open Lightroom , there you should see a folder Preferences.
Please rename the file Lightroom 6 Preferences.agprefs to Lightroom 6 Preferences.agprefsold.
Now please launch Lightroom and see it shows the number, and please make sure you have an image in the Develop Module.
No, unfortunately it does not change anything...
