Thank you for the reply Brood.

Let's see if we can get a bit more information regarding the issue.

When exactly does this crash happen? Do you notice any pattern to it (only when teleporting, only in combat, etc.)?

Just so I understand you first post correctly, The error occurs in both DirectX 9 and 11 modes, correct?

Try deleting the files in the 'My Documents' folder (My Documents > My Games > Final Fantasy XIV), then restarting the game.

If this does not work, can you respond with a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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