-Post a syscheck. (Found on WiiBrew or via Homebrew browser. It puts a .csv file on your SD's root, copy/paste the result.)

More than likely, if the media isn't bad, you just need to patch the IOS Neogamma is using.

Try again with the latest NeoGamma, and post what it says which IOS/cIOS it is using. Maybe it even tells you why it does not work.
