Getting stuck on the Updating Setup Files loading screen may indicate that the Update Agent is having issues installing the game. If you're stuck longer than a few minutes on this screen, follow the troubleshooting steps below:

  1. If you're using a wireless connection, switch to a wired connection and optimize your internet connection to rule out a connection issue.
  2. Review our installation troubleshooting to make sure it is working properly.
  3. Run the Repair Disk utility to resolve hard drive issues.
  4. Programs running in the background can conflict with the Update Agent. Try closing background applications.
