Hello KoharuIyashi, Thank you for posting on the Final Fantasy XIV Technical Support Forums.

According to the error message you are receiving. This is the same thing as a DirectX crash. Below are the steps we would like to suggest trying. Please let us know if any of this works for you.

- Switch to DirectX 9 mode (select ‘Config’ from the launcher)
- Update/reinstall Graphics card drivers
- Disable all programs/overlays running in the background
- Perform a clean boot*
- Set compatibility mode to Windows 7/8**
- Make sure that any anti-virus software they have has the appropriate exceptions
- Install game on C drive (The same drive as the Operating System)

Hope to be of assistance.
