Okay so I have been racking my brain the past week on why names were coming up weird and why certain dialogues were empty. So I was like "Hey lets try and validate the file through the game FFXI config program". So I open up FFXI config and clicked the validate files button and began launching the game as per normal. Guess what? It noticed that a few files were missing. It ran a proper download of all the missing files and everything works again.so here are your steps:

1. Boot up FFXI and find the "Validate game files" button and click it, then exit FFXI Config.
2. Boot up Playonline and let POL run the validation process.

If this doesnt work for you try reinstalling the game entirely.
