I received your email and I have followed your directions for re-registering this device. You should now be in receipt of the information you asked for to transfer ownership. Thank you.
I have to tell you, BlueSpray's procedure for re-registering a second (third...)-hand device needs review. Your current process sets the bar rather high for the new owner. Considering registration has serious impact on device features, it certainly seems to me that a process can (no, must) be devised that does not involve a previous owner.
