I installed wiikey yesterday and it worked great (i played two games), but today when i tried to play game i got error: "unable to read disc" , so I tryed restart my Wii, but noting happened. But when i unplugged my powercable and plugged it back my wiikey worked. My normal games works fine. I use maxell DVD and burned 4X speed. Is my Wiikey installed badly? :'( Or what kind problem this is?
