I am on the newest version now, thank you.
I think I can see what is happening with the audio, but it is very strange. It is somehow layering each track that I have imported in the master channel. the track is 20secs long. So now I might have 6 tracks all layered im the master channel, but I can't clear it. or delete the audio that is in the master audio layer. here is a screen shot:

I can't seem to find a way to clear the master audio track.
Thanks,
