Error ret = (2011)

I am having problems installing the new wad My Life As A Dark Lord. I already saw the other post concerning this error, but the solution posted did not work on mine.

Because the thing is all the previous wii wares that i have installed, like My Life As King or FFC Crystal Defenders 1 and 2, worked perfectly, so i dont understand why i am having trouble installing this one game. So can any1 help me? Is it a bad download or something?

There's a guy who fixed this and what he did was follow the following tutorial. http://www.wiihacks.com/other-faq-gu...s-any-wii.html
