Moviemaker audio files missing

After finishing and saving a project and going back into it later, often times I see that audio files (music) I have used in the project are gone. The audio track has boxes in it with red x’s. Any idea why this happens and is there a way to restore the file without importing it again?

Thanks to anyone for your help.

I don’t know but I hope someone does.

Billyjean. What has happened is you have either deleted the song or removed it. Windows Movie Maker is a vary basic program and doesn’t have the ability for you to move any of the files (even the project file with everything else). Therefore it points all files to the exact location they were initially located.
