Wav form not appearing and no sound - but file info says it's there!

Saved wav file (info says data is all there) opens in Adobe Audition but there is no wave form and no sound, though markers are there, meta data is there. I press play and it runs but obviously no sound. I am at the very end of recording a 15 chapter book in Adobe Audition. This is the last chapter doing this, when I tried to open it.  Every other chapter opens just fine. Anyone know how to recover/restore this file??!
