Unnessessary IP Ban?

[Marishi-Ten]

Square doesn't ban IP's, they ban accounts. Version check errors can be caused by:

Firewall
Port Forwarding
Corrupted Boot File
Antivirus (if you have Norton/Symantec make sure it's on)
Poor internet connection
UAC set too high
Permissions not set correctly in Windows
Recent Windows update

Without the error code of the version check, it's hard to tell. There are work arounds for the above issues that you can try:

If you have a firewall on your router, turn it off
Port Forward the port range XIV uses on your router (UDP 55296-55551 TCP 80, 8080, 443, 55296-55551)
Get a known good boot folder (Reddit) and replace it with the one in Program Files (x86) > SQUARE ENIX > Final Fantasy XIV: A Realm Reborn
Set your UAC down to as low as it will go
Make sure you have R/W permissions for your machine
Roll back to a previous state of Windows (before update)

1 - Router doesn't have a firewall
2 - ...what?
3 - How does this prevent the unique connection blocking?
4 - I'm sure I've done this before for a different reason, but i'll double check
5 - I do
6 - If this, for whatever reason, is the only way to fix, then I need to stop playing

Also, the errors are [30605][10009][10020]
