hi it took me 6 hours to do this yesterday i'm guessing your running vista?
do yourself a favour go to a friends house and just use their xp computer and it will be all done in 10 mins.
nemesis will only work on certain vistas with certain drivers installed and no one can figure out why or where these drivers can be found.
i trawled the net for answers and found nothing then i thought my other half has a brand new lap top with vista on and it worked first time this is def beacause she hardly does anything on it no software updates etc.
it is def worth debranding but make it hassle free use xp!!
