hi
we just speak on the phone.
let's try this.
install 2.0.0.27 kick start cd, this should automatically download the new packages from 2.0.0.29 cd, which is now the current one.
after you finnish this, go to main menu and click pluto logo from botom left.
you should see now that version is 2.0.0.29
waiting for your feedback,
we are clueless why you can't boot 2.0.0.28 and 2.0.0.29 are not booting on your machine, since it's the same cd, nothing changed.
did you try to use another computer?
