i'm running it on 2 laptops, well i'm trying too anyway. it won't work on any of them but it does work fine on my xp p.c.
both laptops are running the nvidia mobile cards, one is the older version, this laptop is a athlon 1.2, 512mb etc. plentty of spec.

the other is a new advent 2.8p4. with the new nvidia mobile card onboard, i can't remeber the name of the thing. again plenty of spec.

i have tried everything i can think of, reconfiguring the port, different software etc. one thing i did notice though is if i plug the cord into the tx and go into the control menu where the red bars are they don't move, but if i watch the lines and unplug and plug the cord back into the tx then the bars do move up for a milli sec. so the sim is seeing the tx for a fraction of a sec when the cord is initially plugged in. still won't let me use it though.

sorry i can't be of more help, i'm going to dual boot with 2000 pro, that shold solve it i think.

cheers
