I have your version (184.108.40.206) running on my 6.0 system. If I recall, when I was installing skype, I did a lot of downloading and stuff before learning of stretchedthin's video. So I did my best to clean out all the old skype stuff before resorting to the video. I think it worked right "out of the box" after I followed the video exactly. Don't know why you are having trouble. Only trouble I now have is that sometime the audio is not too clear (Perhaps because I have an old computer), but most of the time audio is very good. Also, when ETM (Event and Task Manager) sounds an alert, Skype dies and has to be restarted. Minor annoyances.
