Pages document saved over accidentally
I thought I had made a copy of a document I wanted to use as a template for a totally unrelated subject. When I got done with the new document, however, and went to open the original one I discovered it no longer existed. I've looked at the instructions for how to recover a prior Version, but when I put my cursor over the title of the open document it doesn't show me any other versions. Can anyone help me recover my original document? It wasn't backed up by time machine or to the cloud.
I'm currently using Pages '09 version 4.3
MacBook Pro, OS X El Capitan (10.11.1)
