My 3-year old son (who was meant to be being watched by my 6-year old!) deleted my "Andrew 2", the most successful attempt I have going. Is there any way that I can get it back? I immediately shut down the program.

I'm playing on a Mac. I backed up my whole hard drive 2 days ago, so if I have to go that route, how do I go about restoring just one player without overwriting the other 4?

Thanks in advance
