Help Needed

It's been a while since i have messed with my Wii, but lately whenever i power it on i get the 'Unable to load Mii Channel Data' error and cannot do anything else, wii motes won't connect to let me exit that popup. At one point in time i had HBC, but now i can't get that to load.

I can boot into priiLoader, but if i try to launch HBC it tells me 'Error autobooting HBC, maybe title not installed'

I can boot into BootMii. However when i try to load HBC from there the system reboots to a black screen. If I try to load the HackMii installer file (bootmini.elf) from BootMii with the SD app, it just freezes.

Specs from priiloader: IOS v70, Systemmenu v481, priiloader v0.4 (r78)

Specs from BootMii: BootMii v1.2, SysMenu: 4.2U boot1b boot2v2

Is there anything i can do to get HBC running again?

Thanks in advance...
