Well, the last thing to do is back up your data and completely reinstall the game. Chances are good that if the above fixes didn`t work for you, then there is a problem with your game setup or system. You can easily back up your data stored in Rocket League and once you`ve done that, just delete the game and download it to your system/console. You will be presented with a number of user and license agreements before the start of the game and acceptance of all this time will help solve your problem. Before you play Rocket League, you have to accept a license agreement. This license agreement is updated occasionally, prompting players to accept each time. If a player does not leave his game so often, he will probably face an error that will prevent him from playing because he has not accepted the new license.
