photog53,
I have been on fiddling around with it and uninstalled Photoshop CC 2014 (on a Mac) Applications > Utilities > Adobe Installers > Uninstall Adobe Photoshop CC 2014. Log out of CC and log back in so that your App window will update and show the INSTALL button for Photoshop. Reinstall it and try to send your Lightroom file to Photoshop. It worked for me, hopefully it will work for you as well.
