I just recently got some Bluetooth compatible headphones for my laptop. My laptop would connect to the headphones using bluetooth but I would hear no noise coming from the headphones. So then I messed around accidentaly deleting the driver that came with my laptop (Dell Studio 1737). Now that I had deleted my driver I installed it again since luckily I had my driver CD that came with my laptop so I used that to reinstall the driver. Now that I reinstalled the driver it said that "Your Bluetooth software license does not include use with this Bluetooth device" or something very similar to that.
Here is various info about my computer
OS: Windows Vista SP1
Bluetooth Card: Dell Wireless 370 Bluetooth Mini-card
Bluetooth Software: WIDCOMM Bluetooth Software 6.1.0.4402
