Mathematica cannot write at the specified location. I work on a PC Intel
Windows XP computer and the syntax for the path to the file is correct in
this specific environment.

Now, either you work also on a PC system and you do not have the permissions
to create a new file directly under the top level of the disk C, or you work
on a Mac or Linux/Unix system and the syntax above is not the correct one.

So, change the file name to a directory/folder in which you have write
access. Or use a file name without any directory/folder specification to use
the default one provided by your system.

I have uploaded an updated notebook at

http://homepages.nyu.edu/~jmg336/mathematica/DianaExportOutput.nb

that identifies the Mathematica version and platform in use, and also the
file name use the default settings from your system.

Regards,
Jean-Marc
