@ Code:L.A 22
To one Boot-Loader v2.0 account you can register only 1 device from each device type. This mean that to one account you can register: Smart-Clip dongle(S-Card), SCout, SigmaKey, PegasusBox, OctopusBox, DreamBox. But it is not possible to register 2 same type devices.
Status Busy mean that you use wrong username to your account or to this account other device is registered.
