I tried installing 15.5 because I am playing Witcher 3 and there is some flickering. I download the driver and install it. It goes through the install process and then the primary screen goes black and the secondary screen turns off because it does not detect DVI connection. I try uninstalling and re-installing but the same thing happens. So I reinstalled 14.12 and I have both screens but I cannot get to CCC. The following error occurs: Please help. Thanks.
