Presenter not playing already added audio or animation

I have recently downloaded adobe presenter 11 and am currently in the trial version. I did this to see if it would be a good fit b4 I purchase.  So far I have created a Power Point with animation and audio (MP3 format) as well as voice recording for narration... None of them play when i view the presentation in presenter.  Is there a way to fix this issue. If not i can use the product. Thanks
