Blank screen issue with OS X 10.11.4!!!!! FIX!!!!!

All I get is a black screen after clicking play on my Mac Pro. It was just working on 10.11.3 less than 10 mins ago. Just installed 10.11.4 and now it doesnt work. And yes I did a complete uninstall and re-install of this from the Mac App Store and still get a blank screen, Please fix this. It is very disapointing and doesnt give me a reason to contine as a subsriber to Netflix.
