So I finally got around to patching Maplestory (I haven't played for about two weeks) and got the corrupted morph.wz file. You get rid of this by deleting and reinstalling, right?
Also, I remember there was a file Nexon "sneaked" into the code that slowed your computer. Panda something. I deleted it before, but don't remember what to delete now.
