Hi Guys have upgraded to Win7 Ultimate from Vista Business running a 64bit OS. I have a problem with an error keeps coming up "unable to start the Bluetooth stack". I have tried reinstalling and updating the Bluetooth driver, still no joy. Checking the Services it's the Bluetooth support service that seems to stop. I restart it and after about 10mins it stops and i get the error messeage "unable to start the Bluetooth stack" . Anyone have any ideas how to fix it. It's driving me up the wall now lol.
