There are two potential fixes to this error.
- You are trying to run Spellbreak on an outdated/deprecated launcher. Make sure you are using the Epic Games launcher. We are no longer using the Steam or the Spellbreak launcher for the game. Current download and installation instructions can be found in our Spellbreak installation FAQ. Once you've downloaded the Epic Games launcher, make sure you are using a 20-digit Spellbreak key. If you played Spellbreak on Steam or the Spellbreak launcher, you should have received a key to replace your older, 16-digit key. These frequently end up in the spam or promotions folders, so make sure to thoroughly search your email, often as far back as early February 2019.
- You are using an old version of Spellbreak on the Epic Games launcher. Ensure you are using the most current version of Spellbreak. The Epic Games Launcher should keep your copy of Spellbreak up to date by default. If not, click the gear to the right of the title and make sure "Auto update" is turned on.
