I installed the demo to boeing 737 800 (default) but whenever I open Voxatc it closes and the recent comms just becomes white. Please help!

I would think twice about buying it as its now abandoned ware. Im using it as I have for years but if I was in the market now I would look elsewhere, it to expensive for no support and you only need to lose your serial number and your out of bussiness

Thanks, I will look for better ATC Addons.
