Been away from the game for about a year.  VOX worked fine in the past, but now when I push T or F12 it doesn't transmit. All keys are mapped correctly, have tried resetv, have tried relogging, have tried restarting CPU, mic works fine on any other game. OS is Windows 8 if that matters. 
If I tune channel 5 to my gameID and hit T I do get the squelch and can hear my own transmission. But not with F12. So no clue what's going on or how to fix it. 
Any help would be appreciated.
