I've dragged and replaced - that was my mistake. You have to delete the older files first. (Or just download the new version, delete the old one and unpack the new) edit: idk anymore, I clearly wasn't doing so well when I installed it eheh, my bad.
Don't feel bad, you aren't the only one with a failed patch install. WinRAR decided to bug and incorrectly unpack my patch files, and my scripts.rpa file was about 3kb smaller than it should have been. One 24 hour crusade to find the source of the bug I was experiencing later, I finally found it.
