I am on my knee's, help please with black screen Wii

I'm in need of a little help/direction

My Wii has a black screen when turned on, i got to this point when I was actaully following this guide 'Completely Virginise and 4.2 Softmodded Wii' when it got to the point of B2, installing all the WAD files, i got an error on the system menu file,i took the sd card out to try another system menu wad file but when i inserted the card back in, the Wii didnt recognise it. Ooops!

My Wiimotes have de-synced so i have a gamecube controller that i can operate, i can also boot into Multi_mod manager through having Bootmi installed(yippee) it is at this point i am lost.

Ive tried a couple of methods of getting things back to normal but no luck,http://www.wiihacks.com/bricked-wii-...tion-here.html & http://www.wiihacks.com/bricked-wii-...-your-wii.html

So i'm out ideas, if anyone can help it would be very much appreciated

Added info, i think i might've been on 4.2e when i tried to 'Virginise' it. It is a European Wii and i've i've no idea the current status with regards to whats installed wad or ISO wise

Any info required i will try to give

Thanks for reading
