How to run MapleStory after server crash Currently, according to everyones experience and mine also, the website login server doesn't work. So, if you still want to play, try running the offline application. What I'm talking about it the GameLauncher.exe It is normally located in C:NexonMaplestoryGameLauncher.exe In Windows Vista and above, run it as an administrator. You should have a Maplestory screen load up. The click 'Play'. A splash screen should pop up. Once the game is open, just login as if you would on the website.
