Pipe error 6 indicates that the mod is either not able to find an active TeamSpeak server, or, if one is enabled, the plug in is not active. Next time you give it a go, boot up TeamSpeak, get into a server, and activate the plugin in TeamSpeak itself. Make sure you're carrying the A/N-PRC 152 radio, and it should work fine and dandy. Nothing is wrong with the mod whatsoever- you just have to activate the TeamSpeak portion manually.
