After a few months I decided to play Maplestory again and after I downloaded and Installed everything I opened maplestory but then the only thing I saw was a blue screen. It doesn't show any error on screen and I can just hear maplestory music in the background. And when I alt tab, i can just go back with using my pc. I tried updating my graphics card etc but that didn't help either. Does anyone know a solution for this problem? BTW: This doesn't happen when im playing any other game like CS:GO but only when playing Maplestory.
