Lost my presentation: all slides were overwritten with wrong content

Here’s my presentation: http://prezi.com/e3muyiysqkzv/?utm_campaign=share&utm_medium=copy

It was almost finished and then I added the last slide (panned out and tried placing a pic over everything) and it changed all previous slides! What do I do? Can I get them back?

Figured it out. Can’t cover all the slides with a pic, even if it’s animated to show up later. I made it smaller in a different location and the rest of the slides were still there underneath.

Hello Ray Porrello, ENFP

there is some information here which may help you regarding layering of objects (send to back or send to front) - see here http://bit.ly/1t2MMPy
