I found a bug that if you are using 2 HDs (in my case, 1 for wii games, hidden with ustealth and 1 for wii U games, both with y cables), that says "hard drive not connected?" and don't installs nothing. if I remove de wii HD, then, it installs OK!
i put in my birth year as 2000 instead of 2008 because i was sleep deprived as FUCK and had trouble reading it. I contacted the admins case that'z what it said.
