Using loaded a video I had edited in Movie Maker 2011.  I can play the video and get great sound on the screen on the left side.  However, only the first frame is displayed on the right side of the screen over and over again for the whole video.  The video was created using MM 2011.  I had MM 2012 on the machine so I uninstalled it and re-installed MM 2011.  Still the same thing.  I cannot see the individual; frames to be able to edit.  I am getting old - what am I doing wrong?  Open for all suggestions.
