cast exception

Hi SDaemon,
by trying out the windows phone example i get a cast excetion and the app shutdown.
I'm testing on a NetCast 4 TV  "LA557408" and on a WP 8.1 smartphone "Nokia 930".

I get the exception in Search.xaml.cs on line 85.
var netCastServiceConfig = (NetcastTvServiceConfig)netCastService.ServiceConfig;

Thank you for your help, 
Br
