Hi David_B,
Thanks for your reply! I've installed PS many times (since version 3, I think), and nothing like this has ever happened. I use and teach PS and LR for a living. The tech person I spoke with told me it is not unusual to have this happen when upgrading to CC 2014.
What happened is that PS CC2014 would not open the image in PS if I used the Photo>Edit In>PS 2014 command unless I used Photo>Edit In>Open as Smart Object. Once opened as a smart object, PS would not save the file. I think it said Error 2.
The tech took control of my computer, removed PS and LR and all the associated files a few times. He told me I'd have to have a high level person help me, but they didn't call me, so I phoned in. After waiting an hour to get to the correct person (not a high level tech) he said he'd have to uninstall everything again and start over and that it would take over an hour. I don't have the time right now to fix it as I'm headed out of town until the end of the month to teach LR.
In the meantime, LR works, but I'm using a trial version that expires in 30 days. It exports to PS ok, but I had to reload all my plug-ins, and apparently LR can't find Photomatix. LR is not installed in my usual applications folder - the tech put it on my system backup drive.
My case number is: 185696477
Thanks so much for your willingness to help!
Terry
