drmark12pa – I have no intentions to harm your system, I was going to look up web services logs and see why the controller unregistered itself. With regards to being cautious on information you provide, only your dealer and a few of us have access to the admin database to do anything with your "account name".I’d be more cautious about providing an email address or controller mac before worrying about the user name. In the meantime, go ahead and proceed with the controller registration process and re-apply the registration code which can be found on your my.control4.com account page. Again I apologize for any confusion this may have caused. Take care, Matt
