iStopMotion Crashed, File Corrupt

Hi there, iStopMotion crashed while I was mid-filming (30 secs), and the file is now corrupt. I saw a previous thread about this and downloaded the Rescue app accordingly, but it hasn’t recovered it properly - any other suggestions gratefully received!

Usual problems - tight deadlines, a week’s work lost etc etc.

Is this a common problem?

Many thanks …

Sorry, saved this in the wrong category - should be iStopMotion for Mac
