  • Players experiencing crash at launch issue on Windows 8.1, this is compatibility and outdated OS issue. Just update your OS and the issue will be fixed for good.
  • As for Windows 10 users, update your OS if you haven’t in a while as the game requires the latest build of the operating system to work.
