It's not a King problem. Mine is now working. Put your Malwarebytes back to the default settings and try it again. It didn't work for me. I do think it is a King problem. Disabling any of Malwarebite's functions is not a viable option.
Hi aggravated, try it now. I just put my default settings back on for Malwarebytes and then the game opened up. So it's working now. I restored the defaults and still have the problem. I do think there may be a Trojan pop-up somewhere in the Candy Crush Saga through Facebook.
