Good afternoon and thank you for posting on the Final Fantasy XIV Technical Support Forums.

I'm not sure about the error message, but the second one suggests your graphics drivers crashed. Can you try a clean reinstall of the graphics card drivers?

You may also want try 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!
