hm, well some ppl only have this kinda tech avaliable, the only prob being that diaomond doesn't support their older stuff. i couldn't get it to work at all in windows XP, that is a major %#@ the shotgun tech software doesn't work in win2k, so say bye bye to auto voice line dropping and stuff. you use two lines, you block two lines completely. in win98 you gotta use a work around to get the shotgun soft to work.
