I really hope they fix the Error 3 code soon. I tried to redeem my code at 04:30 EST this morning, when everyone in the US is asleep, and STILL got the Error 3 code. That tells me that it's not only a congestion issue. I also still can't access my Square Enix Membership account to try the language fix.

I created 2 cases with Tech support. They blew off the first one, telling me to try later. I created another one this morning. Hopefully this gets fixed so I can play tomorrow.
