Since yesterday i randomly get stuck in "Downloading Data" when changing zone.
I searched the forum and tried most of the suggested fix to no avail.
Wiki says sometime deleting the USER folder fixes the problem but it didn't work for me.
After a while the error code: FFXI-3001 pops out, if i press OK to return to main menu i get error code: FFXI-3100 and game closes itself or i just get stuck on black screen with title selection music in the background.
Tried rebooting modem/pc, disabling antivirus, nothing seems to work.
The only way to get back ingame is to either wait 10+ minutes (sometime doesn't even work) or use clear session + unstuck from the website (that still won't let me change zone tho..)
Any idea what's happening?

thats boring can't do anything with this issue seems to happen not for all.

I had this yesterday. I logged on earlier and I can OP warp to my home point now in port windy. But I haven't really tested it yet. Il try later

Having the exact same issue and anytime I zone back into North Sandy it happens again, which means I can't OP warp ... unplayable.

Mine was fine most of today. Did have 1 issue with CN near end. I red dot randomly on there and couldn't log back into CN without black screening. So I unstuck and just avoided CN.

Seems to have fixed itself as of today, maybe it was some server-related issue?
