Maintenance for the week of January 12:
• [COMPLETE] ESO Store and Account System for maintenance – January 14, 9:00AM ET (14:00 UTC) - 12:00PM ET (17:00 UTC)
This happened to me yesterday.I exited the game, reboot the PC, and then it all worked again. However, you may just need to exit the game, and the launcher and then try the launcher again.
If the above does not sort it, then use the Repair option in the Launcher. It's in a drop down, so not prominent where to do this.
Enjoy the game, life is what you really want to be worried about.
