I've followed theinstructions to the letter, I have confirmed that the mic works in windows, I have the key mapping done and confirmed.  I've opened up ports 2000 - 5000 on my router and still noon can hear me.  My mic is checked in every place I can find. muted and boosted, unmuted or un boosted , makes no difference.  Even confirmed that sound are working well in direct X.  Other players can see that I'm trying to transmit.  When I tune myself to a privat channel I can see that I'm trying to transmit.  
I'm running Win 98 and have a Sound Blaster PCI 64D card.  Any help or advice would be greatly appreciated.  Thanks
