Is anyone else having this problem: I downloaded the 4.8 upgrade. I went through the installer. It appeared to install. It did not. I try again. I check at the "which volume to install on" step. It says it requires 0 bytes. ?!? This installer package is over 4MB! I looked through the installer package, there's a couple .gz files of good size (they don't unzip into anything I can use, I assume that's the installer's job). Why will it not install the goods? Please advise.
