What happens if you start up PS CC 2014, first, and then try the Edit In?
Here are a few things to try related to a similar, but not exactly the same problem:
Nothing. I have tried opening CC first and still can't open from Lightroom.
I also deleted the hidden com.adobe.Photoshop.plist file and that did not work. Any other ideas?
What is your OS? Is Lightroom part of your CC subscription?? When you say nothing happens, is Edit in PS greyed out or active and the file just does not open??
Yosemite 10.10.1 is the OS
Everything lights up and I can click on the Edit in line but nothing happens, CC 2014 does not open and I can move freely in LR. I have a Creative Cloud subscription. I have used these programs together for some time now and never had this problem previously. Thanks for the help.
Thanks for your help. The only thing that worked was to uninstall LR and CC 2014 AND delete preferences. After reinstalling the programs worked fine but I still could not Edit in CC 2014 from Lightroom. After restarting the MAC several times the function came back. I'm not sure why but it now works.
