MapleStory closes itself on Windows 8 PC. I had send Nexon a ticket about this, but they say, “you need to perform a clean boot, disable your Antivirus, or Firewall that is preventing you from playing MapleStory.” I performed the clean boot on the PC, but it didn’t work. I had downloaded Windows 10 on Windows 8 PC, and it work. But, it only work once.
