@morriganrant: I'm really sorry. I've already searched around here, though, and could not find anything that helped.

@Morlock: Okay, I'm going to try that now. I hope it works. Thanks for helping!

I'm having a really hard time updating my game. The first time I tried to patch to version 1.8 from version 1.0 I got an error message saying that an invalid file was found; I replaced the "invalid file", tried to patch again, got the error message again(this time with another file), replaced it, etc.
Then I tried patching again, got the error message... again, another invalid file. Okay, I replaced it and thought I could finally patch this thing! But I was wrong. I checked with the Patch Log Viewer and the file that was causing trouble this time was the same as before. I guessed that maybe I had replaced another file or done something wrong so I tried and replaced it again. But I got the error message yet again...
So yeah, now I don't know what to do. This is what the Patch Log Viewer tells me: Applying DFC Update for 'Game\Bin\HelpPages\KOR_KR\Help_Download.html'  Error: err0031 - Invalid File Found.
Can somebody help me?

Also:
* Yes, I checked on Google. I googled this for hours.
* I also checked on Yahoo! Answers, but it sucks.
* My game is arr'd. I got it long ago, but barely played and never bothered to patch it.
* My game's version 1.0.631.
