When I open onenote, all the files are outdated notes

Hi guys, need your help here... My Windows 7 Asus crashed yesterday and I and i had to reinstall Windows. After that is done, all my previous file is moved to a section called windows.old.. now, I would like to open some important documents that I have worked in onenote, previously, I have left most autosave and backup settings untouch. I have since copy the entire folder from my documents to the new documents, backup folder from applocal to the new installed windows. But when I open onenote, all the files are outdated notes that I have worked on a week ago and not the very latest file before my onenote crash I even have saved a most updated onenote file but it is corrupted..
