Consistent Errors '90,000' and '2002'

Hey,

Ever since the Maintenance on the 12th, I've been getting these consistent errors that have basically made it impossible to play. It's on the title screen 'start' is grayed out then I get a '2002' error message that kicks me back to the desktop. And if I am lucky to get into the game, about 2-3 minutes in I am kicked to the title screen with a '90,000' error message. :/

I feel I have tried everything. Reset my computer and my router/broadband. Disabled Anti-Virus/Firewalls. Loaded up the game as Administrator. But with no avail... I have seen quite a lot of complaints regarding these errors and that they could be bugs on Square Enix's end. If so, are there methods around these errors and/or is Square Enix working on a solution?

Thanks.

I am experiencing this today and so far several times starting this morning. This is completely new to me after having played for a couple months now with zero issues. I'm getting random disconnects and the error 90000 window.
This early morning, the server was lagging a bit during fate runs with our group of 8.
I'm on Mateus.
Anyone else getting this?
