Hey I hope it's ok to post these here but I found all the patches for Whiteday all Korean of course but maybe it will help. The one at the top of the list seems to be the final update patch (after running it through a translator) so it checks for whatever needs to be updated. I've not tested any of them tho as our stupid bandwith limit is at it's crappy end so I can't even dl the game just yet. Here's the link:
