I'm aware that this subject has been beaten half to death but I've tried almost every other suggestion posted for people having the same issue and none have worked out so far, so here we go.
Are you running your computer with Japan system locale?: Yes (I have also tried Applocale, doesn't want to open the game either)
Game Name: Dramatical Murder
Description of Problem: The game will not open, the black screen pops up (both with applocale and without) and then disappears after a few seconds
Operating System: Windows 7
Did you download your game from Fuwanovel?: Yes ma'am
What did you already try?: The #1 fix I found for this problem was to try running the game through Applocale, which I did, and the problem remains unchanged.
sdrt4820j has also been installed. Any help would be great. Thanks!
