Sound Not Playing

[EdenC]

I know this isn't VBA related, but my sound is not playing for a clip that I have put into a powerpoint presentation (2007). It worked before, but then a moved the presentation into a different folder (and moved the clip too). Then I deleted the sounds and put them back in, but now though don't play! [Yes, my headphones are working and I can hear other sounds etc.]

Any suggestions?
