could anyone please shed light on the following issues I am having?
Heres the scene:

Im working on a new song for which I have used a template I made for myself. I work on the song. I save it and I close it down. I load it up right away again and there is NO AUDIO !!. I close it down. I open an older song. It plays audio right away. I close it down. I open the new song I just saved a few minutes ago. Now there IS AUDIO this time. I close it down. I open it up again. guess what? there is NO AUDIO

there is something in the new track that is not retaining the audio info for some reason. What could it be??

Any help would be appreciated
