Storyline crashes whilst trying to open large file

Hi All,

Not sure if this issue has previously come up - if so I'm sorry, and maybe someone could point me in the right direction.

Otherwise:

I am trying to open a reasonably large .story file (~120 slides - mostly step by step video) that I was working on a few days ago, however Storyline seems to freeze whilst it is opening every time. Is there a way that I can recover this file so that all the content isn't lost?

Thanks!
