The WAD Manager on my Wii keeps getting error 2011 when installing a WAD! Please help!?

I don't know what to do. My Wii keeps getting error 2011 when installing WADs. I have WAD Manager 1.4. I don't have CIOSFIX or whatever it's called, because I can't find a good download link that's safe. If I need it, can someone please send me a working, safe download link to CIOSFIX.wad or whatever it's called?
