It shouldn't matter, but try opening command prompt and navigating to the folder that everything is in, then try adb reboot bootloader to see if the command itself works. Also, I guess I should ask, did you extract the zip file or just open the zip and try running the batch file? That would cause that error as well.
Wow... and already my dropbox link has been suspended! Good thing my ADrive upload will be done in about 20 minutes. Wonder how many downloads from dropbox it takes to get it suspended?
Heh, no problem. I hope ADrive works OK, this is my first time using it. I just PM'd fastpakr for the link for the torrent so I can help seed that as well.
