Thank you for the reply. We apologize for the delay in our response.

Amadeokristoff, if this only started happening after you upgraded your PC, then this may be where the issue stems from. If you reinstalled Windows when you did this, make sure you install any 'Optional' or 'Recommended' updates that may not be installed automatically.

Where there any other changes to the PC at this time (any other programs installed or updated)?

Have you tried to reinstall the game after experiencing this issue? If you did, did you remove the locally-saved data folder (located My Documents > My Games > Final Fantasy XIV)?

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