Sound File problem

Hii..
I have created three MP3 files using Audacity. The first two loaded into my Pictures to Exe project with no problem, but the third loads in with no volume and a flat line on the wave line.
I have checked the MP3 file itself, and that seems fine, good wave form and play in Audacity and Windows Player no problem. It is just when I load it into my project that I have the problem.
Does anyone have any ideas what I might be doing incorrectly?

Thanks!

I didn't find the right solution from the Internet.
