I've just had a thought Bob.

A reason why the waveform could be blank can be because the imported file is low volume and therefore not loud enough to register in the window.
This often happens when I import a soft vocal WAV or a keyboard soft pad sound.
When this is the case, you'll be able to play the track, but you won't hear it, or it will be barely audible.

The solution is to increase the volume by clicking on EFFECTS and then VOLUME. Click OK to increase the volume to the optimum recommended amount shown.
I usually increase the volume to -5db below optimum, but this is to leave plenty of headroom for mastering.
