My Project and data disappeared suddenly

I created 3 test projects, used it during a training and participants responded to questions so there was data. Today, I logged in and all 3 projects and the data had disappeared. Please support me on having these projects and data back! I did not save it in Library so it is crucial to restore the data and projects.
