If you are disconnected from a battle with the "Bad Service Version" error, this means that your version of the BattlEye anti-cheat system is outdated. To resolve this error, you need to reinstall the BattlEye anti-cheat system with administrator privileges. You can do this as follows:
- In the game folder, locate the BattlEye folder and run the
install_BattlEye.batfile as an administrator.
2. If you are using the Steam version of the game client, also verify the integrity of the game client files in the game's properties on Steam.
