what has happened to my wmv file

I have a small video clip that I use in a powerpoint presentation. For some reason today (whether in the powerpoint or just played directly in windows media) the picture is replaced by a black screen though the sound is OK. It previously worked OK. I have searched help in Microsoft to no avail. Ive done nothing to the original video clip. I am running windows 8.1 and the Microsoft office 10.

try something like klite codec pack
