corrupted file

[microbase]

hello,

I have an important corrupted file.

When i open it, the error message is :

"Erreur lors du chargement du document file : (nom du fichier)
Erreur de lecture
Erreur de format dans le sous-document content.xml du fichier position
2,1599800(ligne,colonne) ..."

I can translate it :
"Error when load document file : (file_name)
Error of read
Error of format in enclosed document content.xml of file position
2,1599800(line,column) ..."

I have corruted this file after an error system during the save phase.

Any body can help me to recover it.

Thanks.
