My ATC was working fine up until a couple days ago.  This only happens with Zibo's 737-800X mod, not the default 737-800 model
When I hit "Enter" to bring up the Air Traffic Control window, it clicks continuously. When I click one of the buttons to trigger the ATC's voice, it glitches momentarily (<1s) and is silent otherwise.  When I readback transmissions, however, my pilot's voice/readback work fine.  The clicking noise occurs throughout.  Also, the text of the ATC communication that is usually in the top left of the screen has disappeared.
