I have been finishing up a paper that is due today and saving it in my Skydrive.  I stopped to take a break and when I came back to my computer I had a message that someone had made changes to the server copy of my document and that Skydrive couldn't save my changes.  It asked if I wanted to keep my copy or the server copy and I chose mine since I was looking at it and it was the most up to date.  When I did this however it took me back to a version of the doc that I had saved this morning deleting over half of my paper.  Is there anyway for me to recover this document?? Someone please help me!
