Excitebots

I'm using a Wiikey and recently got a back-up of this game, I'm playing on a PAL Wii. The game forced a firmware update, and the game played fine for an hour, however it gave me an error message and now refuses to load. My other back-up games work just fine (including a JAP copy of Brawl). Ocarina isn't working either, it gives me the same error message. GeckoOS also gives me a "this is not a valid wii operation" message


I'd really appreciate some help here, thanks in advance



EDIT: Sorry, can this be moved to Wii homebrew?
