Boot Camp Bluetooth Problems?

I got a new bluetooth headset (Cellular Innovations BlueStar HFBLU-1K) and paired it with Mac OS X. It worked great. Then when I went into boot camp (windows 7) and tried to pair it, it didn't work. I turned on the headset and a little balloon in the corner popped up and said: A Bluetooth Device Is Trying To Connect. Allow This?. When I clicked it, I entered in the p for the device and it began to try to install the drivers. Then a balloon popped up and said: Failed to install drivers. Look for Solutions?. When I click this, it tells me to install a driver from the BroadCom website. that didn't work. I even tried reinstalling the boot Camp drivers. That didn't work, either.
