I updated to the latest Lightroom (5.6) and Photoshop 2014 today. Now, when I am in Lightroom and select edit in Photoshop 2014, Photoshop launches, but no photo to edit. If I select to edit as a smart object, it works. Any ideas as to what is causing the problem? Thanks - T.J.
Failing for me also
looks like there is a manual fix here
