Hey guys... I was finally able to solve this issue by completely virginizing my Wii and starting all over..
this is the guide I followed.. hopefully it'll work for other people too...
Thanks a lot to everybody who helped and also to the people who created those tutorials...
that happened to me too.
just reinstall cIOS 249 or get the newest version of usb GX.
usb gx will load into cIOS 36 if there is no cIOS 249.
one and/or the other has to be a cIOS though...
