»Oh... norton... Okay so this is probably due to anti-virus's over-zealousness in deleting files and registry entries pointing to the quarantined files. So basically... it just partly uninstalled your game. To fix this you need to re-register those objects which I'm not sure how to do as I've never done a reinstall through reghacking. I always just copied my XI files and reinstalled the game and then pasted my game files back which would "update" them to a fair degree of accuracy.
regsvr32 ffxi.dll
(I honestly probably wouldn't go this method, as reinstalling POL takes all of about 5 minutes).
Then again I don't use Norton.
