Recover file

Hi I was working on my V8i version last night and the file crashed so I closed down the software and reopened it again. But seems like that part of my 3D model went missing. 
Is there a way to recover it from a certain time? 

I have tried to right click the file > restore previous version but the versions listed are too far back 

Is there anything I can check on my C drive? Or does anyone know where I can allocate the bak files?
