Are you having issues with ACRE?

Yes I was tabbed out when I checked TeamSpeak to see if my PTT button was working. But I have no clue what other program would have taken over the binding. Shit happens I guess, I just hope it will be a rare thing.

Arma itself is the culprit when your ptt keybind doesn't work. We have had it several times (both with TFAR and ACRE) that someone was using some button for PTT that just didn't work once you got into game.

If it happens again i suggest you try changing to voice activated. If nobody can hear you still then that at least rules out that possibility.
