I was about to ask the same question. Having read the info supplied by
'notebook?' I decided to have a go. Logged in as Admin, I typed:
nb = load('sage_notebook/nb.sobj')
and got file not found. After some searching around I found 'sage_notebook'
in my ~/.sage directory, so I tried:
nb = load('/home/bill/.sage/sage_notebook/nb.sobj')
and got:

Any suggestion as to what has gone wrong and how to get out of it?
