All Pie; All the Time.
This weekend I was experiencing an stupid error that would D/C me every 5 min.It was called FFXI-4002. After that it would quit game and give me POL-0512 when it reached POL screen. I browsed all google and found people asking for help on this same matter and people replying saying it was the router, to fix the router, buy another router, stuff like that.I was about to go nuts when I realized my boyfriend's PC was up and he had a BitTorrent up and seeding a lot of files. So I immediately closed the program and voila! Problem solved. And I was almost crying thinking I would have to buy a new router.Maybe this won't help you with your problem, but if someone is downloading lots of stuff on the same connection as you it could affect the game. I googled your error and it was kinda the same answers to the problem I had this weekend, so I guess the solution must be similar.Good luck!
I think it may have been torrent related. I had BT running and seeding something with nobody, apparently, actively downloading it. Shut it down and it's OK now. I'll make sure it's not running while I'm playing, so hopefully that's what it was.
Square Enix says you should try buying Final Fantasy XIV and playing that instead!
