No video...

I downloaded this app for my Mac OS X 10.7.5 to play wmv. videos provided to me by my school. Just like any other program I downloaded from the internet, such as Flip Player and VLC, this application allows me to hear the sound of the video but not to see the video. Unfortunately these videos are for a math course, so sound doesnt really help me in any way.
