I recently took up the Adobe subscription package: Lightroom cc and Photoshop. Initially it worked fine then Lightroom stopped working in that I could not even open it. I went to a local IT expert who worked on it for about an hour. It appeared it was only something that only Adobe could fix.
After spending an hour on the phone with a lady in Delhi India where she took over the computer. It is now fixed to my full satisfaction and she even gave me the stand alone Lightroom for free. On asking why she did that she laughed and said something about me liking to take pictures.
I do believe that she did not think that the cloud version is any good and that is why I now have two versions of lightroom.
Thought that my experience was illuminating.
Cheers Ole
