Saving the File

I am beyond frustrated at this point – anyone who can help, I would appreciate it. I have been working on a project, saving as I go, adding voice to text and almost done, and the system freezes and then says it isn’t responding and not only that, but when I am able to open it back up, everything is gone – nothing saves and I have to start all over.

Captivate 2017 Freezing

I am trying to complete a project and every 30 minutes it freezes and tells me it isn’t responding. This is quite frustrating. Any ideas on why this is happening?
