Mine is not greyed out.
My issue is that the MS Stack recognizes the Pearl through the BT Icon in the Control Panel, but when I go Configure Bluetooth and then Add to connect through Desktop Manager I get the same error that a lot get:
Desktop Manager is unable to locate any Bluetooth devices that support desktop services.
