SAXException: [word/document.xml line 2]: Opening and ending tag mismatch: rPr line 2 and ins!

My file seems corrupted and shows this error can anyone knows how to fix this problem? I’ve seen many reply from others with the same problem but I’m not able to do it alone.

I can send the file via e-mail.

thanks
