My Photoshop Elements 11 crashes all the time.
Working on a Mac OSX 10.8 machine with 16GB RAM
Here is the crashlog:
Go to your username>library>preferences and delete com.adobe.Elements Organizer.11.0.plist and com.adobe.ElementsOrganizer11.plist and any lockfiles with those 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 anything related to PSE. Repair permissions and try again.
Thank you for using pastebin instead of pasting the whole log into a message, incidentally.
Was PSE 11 installed when you upgraded to 10.8, by any chance?
