My prezi goes blank when editing

I have been working on my prezi and now everytime I go to edit it goes blank and an exclamation mark surrounded by a circle comes up. It looks as though I lost my work, but I don’t think so because it is all there before I go to edit. Can anyone help? Thanks!

It goes completely white, I don’t even see the home bar. All I see is an exclamation mark surrounded by a circle. Before I hit edit, everything seems to be downloaded. Then that comes up and I can’t do anything on the screen. I have other prezis that I can go in and edit, so I’m not sure what is going on with this one. If you have any other suggestions that would be great. Thanks!

Here you go:… (edit)… (before edit)

I tried it again and thought it was going to work and then it went blank. Thanks for your help!

Thank you so much for your suggestion! I was able to delete some pictures and resize images and that helped tremendously!
