Lights-Out For Windows Phone 8

I recently bought LO for WP, wich seems a great app.

However there is one function wich keeps greyed out: I can not put my sever to sleep, restart or shut down.

The same is true for my old (V1) homeserver on wich LO is NOT installed, so it's seen as a "device" wich is fine to me. (I can wake V1 up with the app...)

Any suggestions on how to UN-grey the server power functions?
