"No Such Process Error" in Terminal during 1.0.2 Baseband Downgrade

[xlii]

Hey All,
working through this guide: http://modmyi.com/wiki/index.php/Dow...nd_OS_X_iPhone

And when I get to the point where I'm supposed to use terminal to run:
launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist

Terminal replies:
No Such Process

It worked the first time I tried it, but then it turned out norz hadn't managed to get transfered.
Any thoughts?

Edit: I rebooted. A lot. Eventually the whole thing worked.
