Windows Movie Maker (Help urgently needed)

Me and some friends made a movie for school purposes. The filming is finished, and the job of editing was handed over to me. i'm in quite some hurry to finish this thing by tomorow(it now is 7:40 local time) 

The editing has been done, with windows movie maker in Vista, and the movie plays back perfectly in Windows Movie Maker, but when i publish the movie(aka convert it to AVI or some other format, or put it on DVD), the music i inserted continues for too long(it doesn't start late), spoiling the talking scenes in the movie.

I've tried publishing it in different formats, and it still doesn't work.  Screen capturing programs are low quality and only support low frame rates, or doesn't support sound neither. FRAPS also doens't seem to work on my PC.

Any solutions on how to fix this problem would be appriciated

if the music is going for too long then you need to cut it in movie maker.it's in an audio track that you need to cut to be the same length as your video.

cut the audio up and lower the volumes on the part you want to hear talking or delete the part
