Hello @Ajyn,

Using the Repair option on the launcher could resolve your issue.

Players can repair the files for The Elder Scrolls Online on their computer by following the steps below:

• First, start The Elder Scrolls Online launcher by double clicking on the icon on your desktop.
• Wait for the launcher to finish starting.
• If multiple ESO clients are installed and available through the launcher, make sure to have the correct version highlighted by clicking on it once.
• In the middle of the launcher there will be an entry for Game Options next to an icon of a small cog wheel.
• Open the Game Options dropdown menu and click on the option for Repair.
• Allow the launcher to examine all the files for the game. This may take some time.
• If any files are found to have problems, the launcher will re-download those files.

This should allow you to play the game.

If you are still receiving the same error message after following these steps, please contact Customer Support for further assistance.

After re-installing, the game works now.
