Gecko Codes won't work?

I've been trying to use codes for Tales of Symphonia: Dawn of the New World. Whenever I load it through gecko, it says it didn't find any codes...

I have codes though. Does anyone know how to fix it?

If that's too vague I'll try and make it clearer

You need to make sure you have a code downloader and use CheatManager (seperate app) to activate the codes you want to enable. CM will make the gct file from the txt file automatically for you and you should get the option right after you boot a game, to enable or bypass the codes.

I have that. It still didn't work.

After I use CM and try to load the game in Gecko I get a message as the game is loading that says "Cannot find codes"
