Strange. Those are audio files found in Statues Win 0.9\www\audio\se.
Those audio files are used in almost every scene. If they were missing from the start, that problem would've happened sooner. Check the folder maybe something got moved or deleted?
If not, extract the files again somewhere else and completely swap that folder. (Delete the original "se folder" and it's contents and replace it with the freshly extracted copy)
Good luck.
