corrupted file!!!!!!! HELP!

 From:  Val (GAT)
My file that I been working on has gone corrupted, I can open it but it only shows some of the geometry, the rest is missing. I know it is corrupted, because I get an error when I try opening it in Rhino. Also, the file size is larger then the amount of geometry present in the file. Does MoI make backup saves? Michael can you take a look at this file see if there is anything you can do? I think this happened when I forced shut down on my computer and MoI might have still been running in the background.
