I am using Windows 7 on a desktop PC.   I often make photo videos with the help of Windows Movie Maker or sometimes with Windows Photo Story 3.

Normally they work fine, but recently I faced a strange problem.  I imported music to my project which was 3 minutes and 14 seconds in length.  When I played (previewed) I discovered that audio track stopped after 2 minutes and 40 seconds.  Although there were more pictures in line and I had carefully timed them according to music duration of original sound track imported.

Could any one possibly advise what has gone wrong?  Thanks in advance.
