I was curious whether anyone else experienced this. I spent an hour and a half on the phone with an Adobe Tech support guy, on my computer, trying to resolve this issue. so far, no success.
I updated my 2017 last Friday but didn't attempt to run it. Yesterday, when I needed to start on a client's images and discovered that no file will open in Photoshop. doesn't matter whether it's a CR2 or TIF or JPEG or PSD. Photoshop launches, shows the usual start window, MINUS the file icons of previously opened images, and minus the buttons to create or open a file. The menu tabs work on top (I can change preferences, etc.). Basically, any menu tab you can use without an image open works. Now, if I click on File->New, that's another story. Nothing happens... except that when you go to "File" again, "new" is grayed out.
With Adobe, we uninstalled, then reinstalled Photoshop. I even restored from an earlier point (May 27) on Windows and that did nothing. I wish there was a way to go back to 2017.1.0. That worked fine. This is the bullshit about the whole CC experience. In the "old days", one could uninstall if you had updated online and it was buggy and go back to the CD or download of the released version. There seems to be no way to back with CC. I saw Lightroom has an update. I'll stay far, far away from that until this job is over.
