Hacking WBFS Manager descriminates against one game.

[Hooblah2u2]

I've downloaded the .rars like I have for every other game, but this time, when I click browse to add to the "games to be added" list, it loads the bottom bar completely, disappears, and then the game is not on the list. I searched for quite a while but I just couldn't find a solution.

Thanks for your help!

Edit: I tried to unrar the files myself, but the files were corrupt somehow. That's probably the problem...
