Error When Attempting Full Data Recovery

Hello everyone,
I downloaded Top Producer from iTunes for my iPhone. I then installed it but when setting it up I got the error message below. Does anyone know what is happening here? I thought it’s a problem with my device and restarted it to no avail.

General error: StartSession :Errorcode: 268439771 :Error Message: There is no device registered for this license. Please go to the Handheld Manager and register a device first.
