Endpoint Protection Client: No Primary Path and User set

I have had an running installation of UTM9 and Endpoint Protection Clients.
Since two days ago Im not able to install Endpoint Protection Clients successful.

Troubleshooting Steps already done:
- Fresh Installation of UTM9
- Fresh Installation of Windows 7.
- Client installs fine but has no Primary Connection and Login set in the Update Tab.

The Connection to the named Broker in UTM Endpoint Tab is open and the Client trys to connect to the Broker but Registration fails after the 5 Minute timeout.

Also tried to connect over UMTS Stick the same behaviour.

Could it be that my Home License is blocked for some reasons in the Sophos Brokers?
