I re-downloaded a game called Maplestory and it has worked on this computer before but it has been crashing a few minutes after the program has come up. I get into the game, I jump around for a bit, and then a Microsoft Windows messages pops up saying "Maplestory has stopped working." It crashed so many times that I got a popup saying Data Execution Prevention has stopped Maplestory and I have already added the .exe to the exceptions column but it is still causing it to close. Here is a photo, I don't know why it keeps crashing it. I am running on a 64-bit Vista Home Premium.
