Error Code: FFXI-4001
Error Code: POL- 0512

One after the goddamn other.
I can get onto the game and stay on for five minutes at most, but then I get my ass booted from the server and back onto PlayOnline. I called the Tech Support dumbasses and they didn't say anything helpful, they just told me to go the the f**king website and try out the Q&A, which I already did. I've opened up the ports it suggested, attempted removing my firewall entirely, switched from Dynamic to Static IP, plugging into the goddamn modem directly, and then some. I've come up with the same results every....single....time...
I'm all out of ideas now. I'm so close to just giving up on the whole fvcking thing and cancelling my subscription. Does anyone know what I can do to fix this freakin' problem????

Here's the situation.
03/28/04 - 05/17/04 10PM Working perfectly, having fun as a Hume in Ragnarok.

05/18/04 4PM I get my first DC.

05/18/04 4:05 PM I GET DC AGAIN
AND AGAIN
AND AGAIN
AND AGAIN
05/18/04 5PM Find out that router Firmware was updated around 05/18/04 12AM, supposed to be a good thing?

05/19/04 I open and close ports (following all instructions on the website), no results.

05/20/04 5PM I realize the PlayOnline Tech Support is a bunch of bullsh!t and they don't know anything to help you with.

05/20/04 8PM After hours of "1 thing after another" I give up and turn to the forums for assistance.

The day before I had this problem, I had switched from Ragnarok to Seraph to play as a Mithra, if this makes any difference at all...
