I bought photoshop elements through an online vendor and just trying to put it to use. The clone tool does not work at all. I have photoshop elements 5 on my computer, which I kept even after installing version 9. It works.
If that does not work out., just reset the preferences of Editor.
1. Close Elements.
2. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Editor.
3. Continue to hold the keys until you see a message box asking if you want to delete Photoshop Elements settings file; click Yes. Elements will open with default preferences.
