ALL PROJECTS LOST!!! – Grafio 4 - Diagram Maker Review

In the most recent upgrade to Grafio 4, it erased ALL my projects. I have no idea how many hours I have lost and all the research that was attached to each project. My iPad is set to automatic updates and so it did and now I have lost all my information. I will change the 1 star if Grafio can tell me how to restore what i have lost.
