Error 90000, One Character only, from multiple Locations/ISP.

ISPS: Those attempted so far: Comcast, ATT Uverse, Suddenlink

Types: Cable, DSL, Uverse

Speeds: From 2 to 18 Megs.

Date and time: Consistently since service reactivation mid-day PST 10/2/2014

Frequency: 100% of attemped logins on character Odorf Lannister, Server Behemoth. 0% of attempted logins on any other character, any server.

Character: Odorf Lannister

Race: Lalafel M

World: Behemoth

Class/Level: Drg/blm/SMN/Sch/all doh/dol 50.

Area and Coord: Have not been able to log this character in past "Loading" (Moogle mailbag) screen. After ~5 seconds, Error 90000 occurs. 10/2/2014 saw reactivation of my account since laptop burn-out in april of 2014, during titan EX, and was zoned into this instance from the Goblet (Free Company House) Ward 1.

Steps:

1. Re-activated account 10/2/2014. Attempts to log in to character Odorf lannister after re-activation found 100% Error 90000, prior to entering world.
2. Submitted e-ticket (email) on 10/2/2014.
3. Called Service center 10/2/2014. Was directed to port forward. (Though all characters but main could log in, on all servers save for Behemoth). Port forwarding failed.
4. Called Service center 10/3/2014. Was directed to try different ISP. Moved from Suddenlink to ATT Uverse. Issue recurred (All ports open, error 90000 on Odorf lannister only).
5. Had family member log account in from another state, and issue recurred (though they play daily from their port-forwarded comcast connection). Password changed.
6. Chat Support ticket and Telephone Support ticket on 10/3/2014. They referred me to GM's from another wordl.
7. GM Response was to post here.

Additional Details:
Last connection: Extreme Mode Titan Instance, which blew out graphic card in April 2014. Several version updates since then, so somehow stuck either in that instance, or in "Goblet" housing area (which is no longer possible, evidently). Pardon the supposition, but I believe I just need to have this one character transferred from area: Goblet, Ward I to anywhere else that I can legitimately log in from.

Thanks for your help!
