I keep getting told that the "search" button actually works. Search with the keywords: "MOHAA" and "crack" that should get you to the crack.
Also I somehow found links from the home page before you click on the forum page that has an index of all the games that GCW has available. I know it is boring as...HECK...to search but it makes the senior members happy when you learn something yourself...
Goog luck finding the files...
Update: Here try this link:
