Problem with PS10 organizer, it doesn't work. I see the Apple beachball rolling. I'm running 10.8.2 (Mountain Lion) on my iMac, current on updates. Using iPhoto 11, current on updates. I've been using my PS8 to do my work, and saving it to another file, then dragging it to iPhoto to share it. I was dragging my editing photowork to PS10, but it won't allow it any longer. PS10 and PS8 crash every time I close them. Tried uninstalling and reinstalling and didn't help.
Recreate the PSE preferences then.
1. Go to //Users/[User Name]/Library/Preferences/
2. Find the Adobe Photoshop Elements folders for each version
3. Delete the Adove Photoshop Elements [version] Prefs.psp
Go to your username>library>preferences and delete:
Adobe Photoshop Elements 10 paths
Adobe Photoshop Elements 10 settings
and any lockfiles with the same names.
That library is hidden in 10.8. To see it, in the finder click the Go menu and hold down the option key. It will appear below the little house for your user account. While you're in there go to the Saved Application States folder and delete everything for PSE.
It wouldn't hurt to repair permissions, either.
