From what I've been able to find in my own endeavors and from forums and such, are two basic issues and fixes:
1) Make sure you wipe your disk to see if maybe it is trying to update your old install, and go with a clean install.
2) The other possiblility is that your hardware is imcompatible with the distro.(the one that I got from some of the Forums).
you might want to check into the latter first, and then, go to the former.
