Garageband crashing while saving

Hi all,

I was working on a track on Garageband today on my ipad when it suddenly crashed while saving. Now whenever I open it up, it goes back to that song and won't save - so I can't access all my other files! There's an awful lot of work on those files and I really want to get them back but I've no idea how. I've tried switching ipad off and back on, but that hasn't worked - and the files aren't synced up to my PC as I haven't had access to it for a while.

Is there a way to get back to the main screen on garageband? Please someone help, this is so frustrating!

Thanks
