Error 3 may be caused by incorrectly entering your login information. It can also occur if you are unable to accept the End User License Agreement and Terms of Use updates that accompany each patch. Follow these steps to resolve the issue.

  1. If you receive an Error 3 in-game, your digital purchase is still under Starter Account restrictions. If 72 hours have passed since your purchase, change your password to force the account database to refresh.
  2. Make sure you have the latest version of the Desktop App installed.
  3. Delete the Cache Folder to remove any corrupted data.
  4. Add contact information to your account.
  5. If you have a mobile Authenticator, resync it.
  6. Try to log in to the game from a different computer.
  7. Log in to a different play region. For example, if you normally play in The Americas, log in to Europe or Asia. This method will often push a new copy of the EULA and TOU to your computer. Details on how to change your server region are in the Global Play article.
  8. Create a new Administrator account on your computer, then launch the game from it.
