I believe this has something to do with how you have your CD setup. If the installer cannot see the CD "key" then it will blow off with similar requestors to what you are getting. The only solution I've found is to install it by hand (a pain in the arse to do, not to mention you have to find a way to get the CD "key" for your disc) or, re setup how your CD drive is accessed by using uaescsi.device. If that doesn't work, you may have to reinstall OS3.9 to get it to take.
