Error message: the content you wanted to modify was too big or small to fit on the prezi canvas

HI there, there seems to be a path point that it zoomed out too far. I cannot delete the path and every time I try I get this message: "the content you wanted to modify was too big or small to fit on the prezi canvas". I have looked through the previous posts and suggestions - but the options of home, shift left etc do not work for me. Can a prezi person please access my prezi and remove the pesky slide 34?

I now cannot edit the rest of my presentation and I need access to it asap!!!
