Cannot edit my prezi

Edit Subject

I have made a new prezi, saved it, but now when I want to edit it there is a window saying "Please try again to load the page. There were some errors that prevented this Prezi to load. If reloading the page didn't help please visit our support page to get help."
Can somebody help me? What is the problem here? Reloading doesn't help. Will I ever be able to get it again?
