Missing lab notebook

I am missing the following file:

If you get a 404 error when you open that notebook, the “get a clean copy” procedure on the DLS FAQ Thread should still work. Or have you already tried that?

Actually it looks from your forum messages that you were working on that notebook as recently as 2 hours ago. Did you perhaps rename it? If so, the “clean copy” procedure will let you open a new copy and then you can find your old copy and rename it back.

when I click on “work in browser” I get a new browser tab with the following error: " 404 : Not Found

You are requesting a page that does not exist!"

I finally found the right FAQ and recovered my lab file; thanks
