Bc2000 (for the BCF2000 & BCR2000)

Im having a problem with my new bcf2000, it will not communicate with
my PC - win xp, sp1

It arrived yesterday and have installed driver v1.1.1.1 on Win xp
(sp1) and it will not be recognised as a midi device in nuendo 3, also
as a test (even though the firmware is already at latest) I tried the
beringher update tool and the jave editor but it can not detect the
unit when scanning. "error - no appropriate device detected"

oddly i removed the drivers and let windows automatically install its
own and it showed up in nuendo as "USB audio device" and it did
transmit midi data but will not work in mackie mode and I cant get
faders to move.
When I put the v1.1.1.1 and 1.1.1.0 drivers on it doesnt show up as a
device and when in general BC mode nuendo can not detect any midi
activity at all when moving knobs or faders, further backed up by the
fact that the update software can not see the device either so i dont
think its my sequencer.
Why wont the behringer drive allow the device to communicate with my
pc! :(

PLEASE HELP! any help will be very appreciated.
Thanks
