After many problem, I can finally access my game list on my hd, via usb loader gx. Although, when I choose a game, it says

SD/e89r7rhf8 doesn't exist. bla bla bla (I didn't have the time to read it, since it goes away and the game still try to load, but only resulting in a black screen).

I really don't know what to do (I've been searching the whole day, mostly because at first my wii didn't want to see my hd or somehting like that, but now it's fixed) and I have this problem that seems uncommon, since I found nothing similar in my searches.

Can anybody steer me in the right direction? Does anyone knows what is wrong?
