Well, needed to install 2.0 and uninstall twice before Itunes would work (it recognized there was a problem with the audio configuration). Next issue was setting the correct playback devices. Not easy and should have a wizard like 1.0. Finally, I needed to disable my built in speakers in playback devices in order to stop those speakers from playing along with my external speakers, this was not an issue in 1.0. More to come as I notice things.
