We could not load one of the fonts. id: 1100 the reason is: Event [Event type="fontLoadError" bubbles=false cancelable=false eventPhase=2]

After I’ve Downloaded a portable Prezi, I then uzip the file and open the Prezi file. I get this message when I open the offline Prezi file "We could not load one of the fonts. id: 1100 the reason is: Event [Event type="fontLoadError" bubbles=false cancelable=false eventPhase=2]"
