I have a CU 515 and a Dell PC.  I purchased a Kensington Bluetooth adapter Dongle from Best Buy a few months ago.  This arrangement has worked in the past.  Recently it hasnt.  Now my phone will not pair with the PC.  I can search and find the pc with my phone but the phone asks for a passcode when I try to add the pc.  Get the same situation if I try to pair from the pc.  Also just reinstalled the software.  When the system workrd previously, I never had to provide a passcode to pair with the PC.  Only the phone has a passcode.  Anyone have any ideas?

Thanks!
