Problems with editing Prezi

I'm locked out of a Prezi: "There is not enough memory for this prezi to load. Please try to close other tabs and applications and reload the page!" 

There are several high-resolution images in it, and I know there are restrictions on image size; now I can't get into editing mode. I'm not sure what changed. Any ideas? Thanks!
