I've searched high and low for an answer to this and haven't been able to find one, so hopefully someone here can help.
I was working on an essay and had made substantial progress but had to take a break, so I saved it, closed Libreoffice Writer and walked away. When I came back to start work again and opened Libreoffice Writer, it said that the document hadn't been saved and offered me a chance to recover it, which naturally and unthinkingly I took. However, the document it so helpfully restored (and also overwrote my newer version with) was in fact a previous version, so at the moment it looks like I've lost several days' worth of work.
I've checked Ubuntu One, but it only has the updated version. I can't click 'versions' in the file menu of libreoffice. I've followed the instructions on this thread but with no joy (there was nothing in the folder): http://ask.libreoffice.org/en/question/6652/how-to-recover-former-version-of-document/
If anyone has any suggestions, I'd be enormously grateful, because at the moment I'm despairing slightly.
Thanks in advance.
