I used DDU 220.127.116.11 and something went horribly wrong. First, my computer took forever to reboot. For some reason, my DVD drive keeps accessing over and over again. It says it's a "CD Drive" in Windows. The eject button does not work. If I try to access it in my Library, Windows explorer corrupts and hangs. I just did a system restore that DDU made. I'm back into Windows but my DVD drive is still haywire. I'll update this later.
