Sounds like you got it working, I gave up after several days of trying.  Contacted Tech support who told me I had to uninstall then re-install Vue rather than just getting a rendercow update.  after all the installation trouble I had that's just not an option for me.  I will do without hypervue rather than risk loosing my content or messing up Vue in some unknown Murphy way.  I did learn one thing though, I will never do another pre-release, it's not worth the headaches to me.  I will wait till there is a functional physical CD in a box from this point on.
