Delete all of your task force arrowhead mod including; @TFAR, the TFAR folder in your userconfig, and then delete the radio sounds, new radio sounds, old radio sounds, as well as the 32 bit and 64 bit plugins for teamspeak. Now re-install all of it using the exact link the unit gives you. If that doesn't fix it ensure your CBA is up to date (Delete and re-install if needed) and the only other time I have had this issue is running two @CBA folders.
