Reply to mixtrack with tractor le

I purchased the mixtrack that came with tractor le about 3 weeks ago. I cant seem to get the cueing working correctly my cue icoming thru the speakers and head phones. When i push the cue button the music gets louder. I am using my lexicon lambda as my external sound card. The only reason i am using that is the guy at guitar center said that it would work. I have tried to find this tsi file to download i cant seem to find. I am a old school deejay been rocking two turntables and a mixer for the longest.my friend (with heavy arm twisting) convince me to go digital so i bought the mixtrack for $149 it look good enough for me to get the feel of all this deejaying with computer hub bub.. But since i have got it i been madder than a no teeth man at a chicken wing eating contest!!!! Can some one please and really mean please tell me how to map the button,sync the knobs,fix the cue, whatever u call it i need that !!! Help please before i go skeet shooting with a $149 skeets.
P.s every community i check they always talk about the other version of trctoe never le the want u to upgrade i will as soon as i learn the downgrade !!!
