Multiplayer Air traffic controller problem

Hi all,

I have got a strange problem. When I join a server as a pilot, everything works fine, but when I join a serer as a air traffic controller it doesnt reacts. Like, I am joining a server with 20 people on it, And I set my role to Air traffic controller, and I press :join server, it doesnt load, and fsx doesnt works anymore..

When I play on my hosted server as a Air traffic controller everything works fine..

I hope you know the answer!

Greats,

Daan
