DELL Ambassy Security Center

Hi

I get a new Latitude 5440 (W7 64 BIT). I did'n understand the Ambassy Security Center. I start the Programm and add a Windows Authentification with a passwort. When I reboot my Latitude i get the following message: Connect the fingersensor or connect here. My fingersensort ist on bord there is no extern Device! If I click here and put my Windows User and Passwort into the Mask I get the following Message:  This demand don't support.  So I have a big Problem I can not start my System.

Thanks
