Like the title say, I installed my wiikey after the update. I seem to be having problems with the GCOS disc. My wii can't read any of the discs I've burned. I haven't tried any back ups yet but the originals still work. I've burned about 15 discs already of the GCOS disc using either Nero Burning Roms or Img Burn. It may be the media but I heard TDK DVD-R is a good one so I was using it. Should I try +R and see if it works? Might I have to resolder the wiikey? Anyone else installed after the update?
