Samsung Bluetooth not working

Hi
My bluetooth device is not working from today evening.
It shows the bluetooth icon in the right corner of the taskbar but i am not able to send or recieve files and cannot discover other devices too.
The bluetooth device is a Broadcom BCM2070 Bluetooth 3.0 + USB Device
i had the latest driver but i uninstalled it and downloaded the driver from broadcom and tried to install it again . But i get a message as "a later version of WIDCOMM Bluetooth software is already installed on this machine.The setup cannot continue"

I even got a message saying " ERROR : Unable to start bluetooth stack service "
In device manager, the device name also has changed to Generic Bluetooth adapter

Screenshots are provided.

Run driversweep in safe mode to remove the old driver and try again with the new one
