Just finished recording a Powerpoint presentation with audio narration. I would like to do the final editing in Camtasia Studio 7. But the only way I can get the recording to play is to double-click on the recording in the clip bin or drag it to the timeline. Otherwise, preview screen is black. Play head never moves when playing the audio and sound tracks so cannot edit anything. What am I missing here? Even if I move the playhead forward and press play, the playhead goes back to the beginning of the recording when it should play from the point where I placed it, to the end of the recording. It doesn't do anything.
