Adding Text

[zsuzsa]

I've added text to videos I'm making with no problem. For some reason, on m current video, when I try to add a simple text overall at the beginning of the video... my audio track , that I've brought in from my logic sound program, disappears!    Any idea why? The two seem unrelated. Separate tracks. 

I go into Add Text, like I always do. The text box appears and when it does my audio track disappears! Please help me with this. Thanks.
