Need help, Dolphin won't load ISO

[OFWGKTA]

So I was looking for a Gamecube emulator, found Dolphin. Downloaded it.
Downloaded a Wind Waker ISO, the only one I could find WITHOUT having to use a torrent (not a fan of torrents).
So now I get a error message trying to load the ISO, something about a plugin, etc. I'm not a very technical person when it comes to stuff like this, so please excuse me.
But anyway, does anybody know what the problem may be?

You should have read the rules, or at the very least, the box you checked off when registering about not talking about downloading games.
