Please realize that we can’t see your account or your notebooks, so we cannot magically reach in and fix this for you. That error means that the notebook file is missing, of course. So either it never got successfully created or you accidentally deleted it or renamed it. The way to fix that is to go to the “Help” menu in the far upper right corner of the screen. You’ll see that after you get the 404 error. From there click:

Help -> Lab Help -> Get Latest Version

That will give you a clean unmodified copy of the notebook. If you had done some work on the previous version and had renamed it, you may be able to still find the renamed notebook and copy over any completed work. Open the new notebook and then click “File → Open” from there and see if there is another copy with a different name.
