Thanks, for the PM, you know who you are!
My Wiikey2 is connected via wiiclip - i have tried it with and without the wiikey attached - same situation. I'm sure its not bricked because i can go anywhere and do anything except get an app/game to run, Although homebrew fires up as normal.
I have no idea how to remedy the problem given that i cannot run anything even wad manager (1.4 or 1.5). If it were a PC i would reinstall the OS :-)
