Random stop during Movie maker playback

[SilverFreedoms]

While working on my final product I decided to play the video in Movie maker to check the sync. The video stops playing during a certain clip or transition (Happened on 2 videos so far). I tried restarting my movie maker and computer so I could make sure it was not a mere temporary nuisance in Movie maker but the problems is still present. What have I done wrong?

WMM is just buggy that way, I suggest rendering the AMV and watching it, because it keeps getting stuck if you try to play it in WMM.
