The following worked for me:
Close all ESO stuff.
Go to your luncher folder, (usually C:\Program Files (x86)\Zenimax Online\Launcher)
Delete the file "Bethesda.net_Launcher.version.
Reopen your ESO launcher.
Let is do it's little update thing.
Can now play.
Log in and grind, because all quests are bugged, blocking progress!
???
Profit!
