Whatever they did, they messed up something. I was messing around with my Anti-virus Firewall and it seems to stem from that. I've got Bitdefender and this game, for some reason, doesn't seem compatible.

I turn off the firewall, and I can log in and can see everything, but when I turn it on, my Received goes to 0 and I get the 2002 error.

For a bitdefender solution, I went into the application rules in the firewall, highlighted the programs and Removed Rules.

C:\Program Files (x86)\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\boot

It's possible that the idea of excluding this game and all it's components from your firewall may help with the 2002 problem. BUT I can't guarantee that it'll work. All I know is, it was working fine before and after update PLEH.
