Recover .nb file

Is there any way recover an .nb file? I tried to export to .pdf and all the content was lost.

Here’s the error: $ Failed. 6 line of corrupt data deleted.

I executed these two instructions in a new notebook:

Needs[“AuthorTools`”]
NotebookRestore[]

but I got the error above.

CellPrint @ Cell[
BoxData[
StringReplace[“$CellContext`” → “”] @ ToString[
ToExpression @ Get[pathToYourCDF][[1, 1, 1, 1]]
, InputForm
]
]
, “Input”
]

Result is the same:
$Failed

Ion,

If you post the file, maybe we can determine the problem.

Regards,

Neil
