I am having the same or a similar issue, my Guided and and Quick window tabs are black and I don't have the option under the 'window' tab to 'show' anything.
Can you post a screenshot?
In the meanwhile try the following steps:
- Close Elements. 2. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Editor.
- 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.
That did not work, I did click "yes" on the message box to delete the settings file. I still have a black box where the options used to be for "quick" and "guided" tabs.
I suggest you to uninstall(from control panel) and do a fresh installation again.
