Can’t find my diagram

I spent hours creating an OmniGraffle Diagram using the lastest version 7 Pro, now when I open the document I see a blanc page and all my work is gone, I had the file stored on Dropbox and have many versions of if, all versions display nothing when opening the file. the canvas mysteriously disappeared on me. please help.


Our support humans are working reduced hours on account of American holidays, but if you email, someone will help you out when they get the chance. So they can help you most efficiently, please include a screenshot of your entire document and (if the data isn’t sensitive) one of these apparently-blank Graffle documents?

(If this is quite time-sensitive, you may email instead.)

Thank you, will do. I appreciate the direction.
