Here is a process for getting a fresh copy of the notebook.

• Open your current notebook.
• Use the File menu and rename your notebook file.
• Use the “Help” menu and select “Get latest version”. This gives you a fresh copy with the original file name.
• Use the File menu and open the new file.
• Use the Kernel menu and select “Restart & Clear Output”.

Then you can work on the new copy of the notebook.
