Cannot open recovered files. Pls help

[vornok200]

All files on folder "My Documents" was deleted for
unknown reason. I recovered all the files using PC
Inspector File Recovery Program.

Most of the files are okay except for a very important
excel file. When I try to open it, I got the message...

Filename cannot be accessed. The file may be read-only,or
you may be trying to access a read-only location. Or, the
server the document is stored on may not be responding.

I am using Windows XP and Excel 2000. I have tried to
open and repair it in Office XP but I didn't get the
correct data.

Please help.
