Thank you for the reply Aurelius_.

When you got the controller to work, did you start any other programs afterwards? It sounds like it worked, then something was triggered that made it fail the next time.

I'd suggest trying a clean boot. Simply open the task manager and select the 'Start up' tab. Disable everything here and restart the PC. This will make sure that no background processes are interfering with the game.

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