Hi!

Sorry for the late response but I got it fixed!

I tried all of your suggestions to no avail.

So what I did was uninstall the game from Steam. Then I went to the directory it was installed in and remove manually all the remaining files. I made a backup of my characters settings and deleted the folder.

Then I cleaned my PC with CCleaner (apparently some FF XIV stuff was in the registry) and made a complete reboot of my machine after wich I reinstalled the game. At that point the issue was fixed! I restored the characters settings to check if the corrupted file(s) was somewhere in this those but had no problem with them.

Thanks for the help !
