error 90000 since 2/23

[Palladion]

I was playing this just fine before 2/23 and now I can't even get past character lobby. I've tried restarting my router, turning it on and off, I'm currently playing on a wireless connection but I've never had any problems with it so i troubleshooted with a wired connection and I STILL got 90000, I've opened every single port needed. I'm able to play every other online game just fine, but FF14 seems to only have this problem.

Then I went to chat support and told me it was an ISP problem. So I went to my ISP and they told me it was a server-side problem. I did this TWICE and they still passed me off to each other. WTF?

Allow me to elaborate on what I was told by both chat support from SE and my ISP. SE support told me it was still a problem with my ISP since there seemed to be a problem between my client and their servers and when I told them that I can play all other online games with the exception of FF14 just fine, they passed it off like FF14 was a very special case by saying no other game transmits as much data as FF14, so it wasn't their problem. The chat support for my ISP told me it was a server-side problem because if I can play other online games with no problems, the problem must lie in THEIR servers.

This is so frustrating that I'm going to be cancelling my account in the next few days if this isn't addressed.
