Plese try after deleting the preference file of PSE Editor.
Press ctrl+Alt+shift just before application launch, and press yes to delete the preferece file.
Thank you for the suggestion, but I have already tried this. I tried it again just in case, but the computer crashed again. I can't get to EDIT in order to delete the preference file. Maybe you have another way to delete it?
you can manually delete the preferece file located at
C:\Users\[username]\AppData\Roaming\Adobe\Photoshop Elements\8.0\Editor\Adobe Photoshop Elements 8 pref file.
If you don't find the location press ctrl +r type %appdata% to get the Roaming path.
I manually deleted the preference file as suggested—I put it in the trash and emptied the trash—but when I started Elements 8 and tried to go to EDIT, my computer crashed again.
