Unable to locate character configuration

Hello,

yesterday I cut out my screenshots folder because my PC was full(sadly "My Games" folder is saved on my SSD where my Windows is saved instead of my HDD with more space).

I wanted to log into my account and I had to redo all my configuration(graphics, sounds etc) and had to choose a Data Center. Now I wanted to log in but it says "unable to locate character configuration".
I read some thread which was talking about a Anti-Virus program but I think for me it's the issue with the screenshot folder.

Do I have to reinstall my game again or can I do something else? Sorry I am not good with software and I really don't know what to do.
I would be really happy for help and solutions!

I am able to play the game, I redid my interface and overall configurations. Screenshots do work and they are saved in the new folder I assigned.

But my questions is: should I reinstall FFXIV? Or will it work like that?

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

From what you've described, it sounds like the folder that has all of your locally-saved data was changed or removed. This folder is separate from the install folder. If you have reset your settings, then you don't need to reinstall anything.
