Can't scroll down the menu of Gecko OS

[OniReek]

Hey i'm kind of new here, but I already have a problem.
I've installed Gecko Os which launches just fine, but when I get to the menu, it seems the wiimotes are turning themselves off...and there's absolutely no way I can navigate the menu, even with a classic controller pluged in.
I've been looking on Google for a solution, but found nothing.
A little help is more than welcome.
Thanks!
