problem with finished project; hangs on one frame

[losingmymind]

For a year now I've been working on a slide show with music and transitions
for my in-laws 50th anniversary. I've saved it to my computer and a cd, but
when I try to play them they only get so far (one gets 10 min in and the
other gets halfway through the 47 min.) then it freezes on one frame and
continues to play the music. I'm not even sure if it's saved right. It's
impossible for me to start over, but is there any way to export it to another
program that works better. I don't have much computer knowledge, so any help
would be appreciated. I eventually want to burn it to dvd, so I need help
with that, too.
Thanks

A first place to start is to see if you have incompatible source (video
and/or audio) files. Try this URL:

Another trick that sometimes works is to uncheck the boxes in Tools|
Options| Compatibility.
