I downloaded Drive Booster from Google, the free program (you can choose the premium pack), and started to analyze what drivers my pc needed and started to up date them. And after cleaning and optimize BL start to make it´s magic again.
So, maybe you need to update your graphics and drivers, well, that was my problem...I did yesterday and I have no problems since them.
You´ll find some Driver Booster´s tutorials in YouTube, and is very easy to manage... I highly recommend, just to optimize and update drivers in your pc...and this functions of BL will appears again. Hope helps you, in my case was absolutly fantastic. Just working with the free pack, for sure i will pay for premium...It´s not a commercial...Just I´m trying to help you out. Regards;
