Homebrew Channel Error: This is not a valid wii application

I get the above error when i try to launch certain applications like Tetris Wii and Gecko Region Free. I installed the Homebrew channel fine using the Twilight Hack, but i can't seem to load some applications. I don't have any memory cards in either As ScummVM loads fine. I really want this for Gecko as i want to import some titles so i really need for that to work. Any helpful information at all, i'm new to this.

Thanks for looking.

Not long after i posted this i fixed it. I downloaded the latest Gecko OS and replaced the old one with it. Works fine now.

A quick question, instead of making another topic. Are all games compatible with the Gecko OS? Reason i'm asking is i don't have any import games to test it out on yet and the short lived Wii Freeloader wasn't.

I installed the update recently (just now) and now it gives me this error with EVERY Gecko vetion, the Occarina, infact the only program I can run is duck hunt. and I tried to remove it but the page it lead me to was blank so I cant remove it.

I just want to use Occarina, Gecko if I have to as everyone says thats the new occarina, but I prefer to stick to what I know. any anyone help me here, prefrably ASAP
