Running LR 5.7.1 64 bit on Windows 7 Pro on a Dell XPS-8700 desktop. My presets have performed great since starting with LR 5.0 running through the 5.7.1 upgrade, but over the last 3 months, ~1/2 of the presets no longer work. Even though the file name still shows, they are not available on the preset drop down list. When I check the Development Presets folder, they are still there, but the color of of non-working presets have changed from black to green. I have tried uninstalling LR 5.7.1 and replacing it first with 5.0, then 5.6 and 5.7 versions with no improvement. I also have a Dell 3540 laptop running Windows 7 Pro and have not had any of these preset problems. HELP PLEASE!!
Good morning and most importantly THANK YOU for ALL your help!! Your suggestion worked perfectly and I have access to all presets again!
Very best wishes,
