Fedora 13 released

And I'll further add... that the restart of the download on reboot that you are seeing may actually be expected because its actually the anaconda installer doing the download. And anaconda is downloading to the virtual filesystem in ram.. not to a harddisk location.

Please check the amount of free space in /boot. I think if you can free up enough space in /boot preupgrade will work as expected..and will download the necessary installer image so the reboot into the installer will run as expected without touching the network at all.
