Somebody please help I downloaded the game from https://fuwanovel.net/novels/dramatical-murder . It was working fine all day. The saves worked, and i had no problems. I exited the game awhile ago, And now it wont work. When i start it up, Its a black screen, It thens goes white and the fades back to black. Sometimes the title screen will start to show, but dissapear back to the black screen. My Locale is switched, i tried running the sdActi like most people suggested, it it does the same thing still. I don't want to have to uninstall and then re-install the game, as it took about two days for my laptop to download it. Is there anyway to fix this so i dont lose my saves? If i have to, i will restart everything, I just need to know if i can fix it or not.
