Restore previous version of prezi

Hello,

I have managed to delete all the content of my prezi by clicking on the outermost frame and pressing delete. Somehow that version was saved.

Please, please can you restore the previous version? It will be obvious which one it is.
I've gone from having a complete prezi to nothing but the background and one little orphan circle.


Thanks,
Vanessa
