I didn't see this issue here so I've sent in a ticket.
From Steam the launcher will not launch. It says it's running. For a split second. Then "Running" vanishes. Still no launcher.

When launching from the .exe file it looks GREAT! Until my absolutely 100% correct user name and password are denied. Repeatedly. A side effect of linking Steam and ESO that results when Steam is borked? Maybe?

I've already been
highly unimpressed with how unprepared Zenimax has been for the very normal summer rush that
all popular games endure when kids are out of school. This is icing on the my-money-is-going-elsewhere cake.
Has anyone else been experiencing
this same error?
