so basically, i can not start MapleRoyals without being in fullscreen, which is the bad resolution fully stretched out on my screen and i have to tab out every time, which is kind of annoying. i get the -2147467259 error and do not have dinput8.dll in my folder, disabled anti virus and reinstalled, no result. i'm on windows 7. does anyone have a potential fix? please let me know thanks in advance.
Try updating your graphic and lan drivers. Also check if your screen refresh rate is fixed to 60 Hz not 59 Hz.
