Wad manager does not install correctly

i have installed a .wad on my wii using wad manager but when I enter it, it goes back to the wii menu. I think it dos'nt install it correctly because it's to large (it dos'nt install some of the contents).
the .wad is "sonic the hedgehog 4 episode 1"
(i have also tried dolphin & convrting the .wad to an .iso, niether worked)
can some one help me?

I do believe there are other WAD managers for the Wii, if you check the Wii Homebrew wiki. Try those and check if anything works? Other than that, attempt getting a different WAD as the WAD you may be using is corrupt.
