Premiere elements 8 music won't play

I have a video all put together with over 400 photos. I reduced them in size below 1000 x 1000. I added like 8 songs. All songs but one will play. The file is not corrupt, as it plays on my computer. I tried another song in that part of the video, and that one won't play either. I need this video by tomorrow for a funeral service. Any help appreciated!!!
