a video wanting to post!

i made a video dedicated to my ever loving beautiful classmates but until now i can't post it yet. it is already done, it was just simple really but the music that i placed won't play. i kept on checking what's wrong and until now i don't know. as i tried to edit some video effects the music played, then it stopped after a few minutes. i really don't know what's wrong. i just want to post it but i would be boring to look at a slideshow for 8 minutes without any music, right? so i won't give up i hope it will be fixed soon.
