Hi Hagar,

Thanks for posting on the Support Community.

With regard to this error message, please can you confirm what the media was that was used in the flipchart? 

For example, was this an old video file that was embedded into the flipchart? If so, its possible if that video file is no longer available on the computer in the same location as when this was originally located you may get this error. 

Kind regards,
Adam
