Chose New game thinking it would create a parralel game but has deleted my entitre save.

I've been playing episode 16, and didn't manage to do any of the "trade only" evolutions. When I downloaded episode 17 I thought I'd try it. I mistakenly thought New game would create a new game in parallel with my other game so I created a new game so I could trade with myself. However my old save game is now gone. Is there any way to get it back? If not is there any way to get a save that has already beaten episode 16 as I don't really want to retread so much ground?

You should have some back up saves in "save" folder. With name of your character and time played. 

Also, haven't you heard about link stones?
