I'd be happy to look into this if you can provide me with the email you used, your full name, and order number, I've tried searching our ticket system for gh2k and can't find anything.
Thanks for looking into it. I've sent you a PM.
I found it with thomas's help, The control unit on the blade died. Not sure why out software did not report it, but it will be back up shortly (we have spares so we can have it RMA'ed)
