Bluetooth driver not working

I have just upgraded Bootcamp to ver 1.4. After the restart, I cold not connect the wireless keyboard and mouse. I checked the bluetooth driver and it said it could not be loaded and might be corrupted. I reinstalled the driver from the CD created by Bootcamp assistant without improvement. Have now rolled it back to version 1.0 which seems to be working, but I have to reconnect with the passkey all the time. Has anyone had similar problems or did your wireless keyyboard and mouse just work in Windows with Bootcamp 1.4?
