I created an entire my prezi on ecology and now it is blank when I try to open it.

I created a prezi on ecology. This morning, when I tried to open it to start teaching class, it was blank. It opens as just the template I chose but there is no writing, work, or frames. I have tried opening it on several different computers around school and also on my phone with zero luck. I have no idea what happened. I was not doing anything strange. I turned on my computer, opened chrome, went to prezi, logged in and then this is the only one of my prezis that is blank!
Please help! Thanks!! Here is the link to my prezi: http://prezi.com/xzmxiixrpqiy/ecology/
