Thank you for the reply Perpetualgamer. I apologize for the delay in our response.

There are a few more troubleshooting steps to try if you haven't already:

1) Set the compatibility mode to Windows 7. Right-click on the ffxivboot.exe file and select ‘Properties.’ Then select the ‘Compatibility’ tab and choose Windows 7.

2) Double-check that your anti-virus/firewall has the appropriate exceptions for Final Fantasy XIV.

3) If any part of your PC is overclocked (including factory overclocks), remove them. Check that your PC is not overheating.

4) Disable all overlays (Geforce Experience, Steam overlay, etc.) that may be active while you are playing the game.

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
