The one menu in the develop window is not allowing me full usage as it did in the trial version. I cannot adjust exposure, highlights, shadows, whites, blacks, vibrance, clarity, sharpness etc,
I noticed that it was disabled when trial version expired its 30 days and now after purchase seems to have remained with limited function?
Moving this discussion to the Photoshop Lightroom forum.
If you purchased the Photoshop Creative Cloud package which includes Lightroom you need to uninstall the existing version of Lightroom, this process will just remove the actual application and will not interfere with your Catalog, preferences or personal files. Then close and restart the Adobe Creative Cloud Application Manager and it should offer Lightroom for download and installation. Proceed to download and run the installation package. It should complete and every thing should be fine.
