Sound truncates on Windows XP

[Lukester]

Hi

I use Windows XP for using Microsoft Encarta Encyclopedia 99. It may be a bit outdated, but just because something is a bit outdated does not necessarily mean it has lost its charm. The problem I have with Windows XP is that the sound truncates just before the sound clip ends. For example, when I hear the sound clip that is supposed to go "That's one small step for man. One giant leap for mankind.", it actually goes "That's one small step for man. One giant leap for--" and all the other sound clip ends just like that and it is very annoying. I would appreciate your help.
