Need Prezi reverted. (work recovered)

I need my prezi reverted to a previous version. (It did not save correctly, gave me an error message.)

http://prezi.com/meyk9zkxvtdk/edit/#8

The area in question is currently the 13th-34th path points, titled "components".

Two main changes I was working on:
1. move "standards based projects" circle to the left and branch the circle on the right into 3 circles.

2. Change the path points to include the "student notes/etc" circle after the "standards based art projects.

I will work on something else for about an hour, hoping that you can revert it by then. Thank you for helping me to remain productive.

I was working on it with a coworker and his edits were saved, but mine over the last half hour were not.
