I've got same modem, but using it with XP, you do need to use the set up cd first, before connecting the modem, at least on XP, sotry again, first going to add/remove programmes and delete broadjump client foundation.
Then go to start, run, type in regedit, then go to edit, down to find, type in NTL in Find What, then after it finds entries, right mouse click each and every one and delete, keep doing this untill it finds no more.
Now try again, installing modem using setup cd, and follow on screen prompts.
Good luck.
