new portatree timing syst

we got out new syst and spent most of last night trying to set it up:CRY: :CRY: , got it hokd to the laptop and all the sensors lined up in a big shop to simulate a track.
cant get the darned thing to work. the diagnostic says all is good and working but as soon as we set it up for a run and some one walks and stages the red light come on immediatly. man what a hassle,were doing somehting wrong and cant figure it out.
anybody out there work at a track that would have some suggestios or answers.
they are not open till tomorow and we have to try to get this darned thing working by friday pm for raceday sat morning.

well hate to diss the portatree so i will not, we got it working fine had a good race day all worked well but it wasnt for a gear head. you got to be puter savvey to figure the thing out to make it work.
once we had it running its a great product and works great,
