[H] Logitech Bluetooth trouble

[Winterlight]

My primary three year old computer has been using Logitech cordless 
mouse/keyboad combinations since I built it. I started with a optical 
mouse set, and then moved on to a Laser mouse set (which I love), and 
just recently attempted to upgrade to a MX5000 which is a newer laser 
mouse with bluetooth, a LCD display on the keyboard and a bluetooth hub.

I have been unable to get it installed. The bluetooth stuff just 
chokes, plus the mouse/keyboard keeps disconnecting... of course, I 
can't get pass the bluetooth part of the install. I am doing a clean 
install, and I disable anti virus, firewall everything thing I can 
stop from loading at boot up. And I boot up clean, and then attempt 
a  install.

But I can't get it installed. First time I have ever had a problem 
with Logitech. I see lots of older complaints about the MX5000 but it 
has been around for over a year and you think they would of corrected 
them by now? Anybody have any personal experience with this product 
or Logitech bluetooh. I am just about to give up trying.
