Just in case anyone else has trouble with the 5/09/11 update...
If you're on a PC and get the POL-1153 error during the update (data verification) process, you can fix this by shutting down the POL viewer, then deleting the patch.ver file in the Program Files/PlayOnline/SquareEnix/Final Fantasy XI folder on your hard drive and then restarting the update process.
Happy Version Update Day! w00taru! :cool:
