I'm trying to set up my flex. I brought the unit home, from the store, and proceeded through the setup process. After "verifying my account information" I get an XRE-00251 error. I called support and they tried to help. After 4 people, they told me to take it back to the store and replace it. Did that and tried to set up the new device...same error. Obviously, something is not set right in my account info, but there is no message to indicate what that is...and calling in is no help - all they do is troubleshoot the device.
