I have had Nomad up and running for a while. I hadn't used it in a bit and went to transfer some programs for an upcoming trip. I keep getting the account validation required message (AR/3004). I have uninstalled and re-installed the application to no avail. I have also unplugged and plugged back in the Nomad. I have a macbook air running OSX version 10.8.2 and Nomad version 1.0.0. Any further ideas or do I need to call DirecTV?
