I have a copy of all the files that were updated (that I could find) in this post: http://forum.square-enix.com/ffxiv/t...=1#post1099923 and a copy of the updated boot folder in this one: http://forum.square-enix.com/ffxiv/t...=1#post1098250

I've not had any update issues myself so I have no idea if that will fix anything, or if it will break things (back up any files you will be replacing) but you could give it a try.
