network problems

I have installed VoxATC 7.41 (main program) on the FSX SP2 server. The VoxATC panel was installed into the aircraft I was using. VoxATC Remote Panel and VoxATC Net Server is installed on the client.

I ran the VoxATC Net Server and VoxATC Network Client on the server. Then, I ran and enabled the VoxATC Panel on the client. The VoxATC Panel of the VC was not enabled. The traffic was injecting into FSX and I could hear the AI requesting clearence. The mic on the Laptop was activated and working. I clicked the button on my joystick and also tried it via the delete key to talk to ATC. I couldn't hear the sound of pressing the button and ATC didn't respond. The joystick....exe of VoxATC showed correctly when I pressed and released that button.

I have to use the mic of my Laptop, don't I?

Thereafter, I removed the VoxATC Panel from the aircraft to run it via the VoxATC Panel Proxy and also installed VoxATCRemote Panel on the server. When I am trying to run VoxATC Panel Proxy of the server I get two application error:
