Photoshop Elements 4.0 now refuses to run on my Intel Macbook (10.4.10). It used to work flawlessly. One day, it just refused to open. The loading screen would come up, then it would crash and say "Photoshop Elements has unexpectedly quit." Nothing changed on my computer between the last time I used and when it started to crash. No new software, no updates etc. I have tried doing these things to fix the problem:
-Rebooting
-Deleting the Photoshop Elements .plist file
-Using a different user account on my computer
-Repairing permissions on my hard drive
-Uninstalling Photoshop Elements and reinstalling it
All of which have failed to work. Nothing I have done has been able to work.
