[Solved] File format error found at SAXParse

[Coffaro]

Hi, I did a big mistake. I saved a file in docx format and now I cannot open it. This is the message:

SAXParseException: '[word/document.xml line 2]: Attribute w:cstheme redefined
', Stream 'word/document.xml', Line 2, Column 92211(riga,colonna).

I tried to open it in every way, but it doesn't work, It's a very important document (part of a phd thesis). Please help me! The file is too big to be attached (210 kb).

Thank you very much

Then upload the file to a file sharing site and post the URL here.

Make a copy of the file, change the extension to .zip, open the archive, extract and open document.xml in an xml editor, or in a plain text editor if the xml editor refuses to open it (because it's not valid xml). Search for Attribute w:cstheme and remove the second or first definition. Save, insert in the archive over the old version, rename to odt, try to open again.
You can also upload at a file sharing host and provide a link here.

Search for Attribute w:cstheme and remove the second or first definition.

I tried to do it, but now it say "general error". May you explain me what I must remove exactly?
Thanks a lot!
