Unable to save

I am unable to save my Prezi. When I go to save it, a window pops up saying “Most frequent error of flash apps: security error. But we don’t know what it means at this time.” Under details, it says “id: 300 the reason is: ErrorEvent securityError Error #2048”. I don’t know how to fix this problem.

This is an online editor, the computer is a windows xp, the browser is google chrome, and the url of the prezi is http://prezi.com/awgzje11tjoa/edit/#0

It is now letting me save, but this makes me nervous to work in Prezi, since I don’t know what caused the problem or how to fix it.
