Unable to load any Prezi PreziError id: 2010 the reason is: ErrorEvent securityError Error #2048

hi, 
I can’t load any Prezi today (either mine or other ones online) with the message 
Technical details:id: 2000 the reason is: PreziError id: 2010 the reason is: ErrorEvent securityError Error #2048
All the templates seem to have disappeared (on any Prezi), as the images on the Prezi I was trying to edit… I’m using the same copmputer as always…
Thanks in advance !

I am having the same problem Error #2048. I’ve updated flash, used multiple different computers and browsers and still keep getting the error. I have a professional presentation today at 2! PLEASE HELP!
