If you can not find any more info about it, I would try re-install via Steam (maybe first the 'check file integrity' or whatever it was called in Steam), and not install the downloadable 'windoze 7 POL Viewer' at all, unless confirmed that it is indeed necessary.


If you had the game files update for hours, you may want to back up the game folder as the newly installed folder can be replaced with the one with the updated files, thus avoiding the need to download the files again.

It does take quite a while to just copy the files over as well. Would be best if you had a different hard-drive to copy them from. Alternatively, rename / move the FFXI-folder with updated files, install FFXI, remove the newly installed folder and move / rename the one with the update files back.

That's more for future reference for anyone having to re-install the game for whatever reason and not particularly something you need to get into to get your problem solved.
