Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

We apologize for any inconvenience that has occurred when playing Final Fantasy XIV. In the event that you should require a reinstallation of FINAL FANTASY XIV, please note that the game files and the local in-game configuration files are separate. A uninstall/reinstall should not affect the configuration files as those are saved in the 'FINAL FANTASY XIV - A Realm Reborn' folder located in Documents > My Games or if you use OneDrive > Documents > My Games file paths. To be extra safe, you may also visit the settings of the FINAL FANTASY XIV launcher and use the 'Back Up Tool' to back up your interface settings as well.

We hope this information has been helpful. Thank you once again for visiting the Final Fantasy XIV Technical Support Forums!
