Diablo 1 HD Hellfire Mod | Awake

Hi, I added that file to my registry and it solved the problem, but it seems to have messed up graphics in windows, for example youtube videos are now multicolor. Is there any way to change it back, to remove it from registry or is there another file to set the graphics to defauld settings? thx

well, problem solved - for anyone with the same problem, just reinstall graphics drivers with clean installation
