When I edit in my movie maker, the preview of movie has no any animation or picture shown, is black screen...I wonder why...

My movie maker and windows media player are the latest version, the raw video can be played in windows media player.

I downloaded k-lite codec pack and used Media Info the check, but I don't know to to fix this....

My graphic card is NVIDIA brand, but issues persist.....

Now there is this code:  catalyst control center：host application has stop

Help me pls T.T
