This error means that you are running a version of the game client that is not concordant to the publicly available version. Please update your game and try again.
This update is typically automatic, but if you find that it hasn't occurred, here's how you can manually initiate it:
- For the game launcher or Steam: trying to relaunch them is usually a good first step
If it's still not working, you could try the following methods:
- For the game launcher: Shifting your focus from the launcher to another application (or your desktop) and then back to the launcher can trigger a check for client updates.
- For the Steam app: you have the option to perform a verify integrity of game files process
If no update is available or you have updated and the problem persist, please visit our service status section.
