Re-download hackshield from the MapleStory website, and then move the file after you unzipped it into your MapleStory folder (replacing the old HS if needed).

If it were that simple, this wouldn't be posted. That's Nexon's solution, and it certainly seems as if anyone would go there for solutions first.

I am having teh same problem after patching the game normally after the maintenance, and have tried that solution.
