Hey, what is up. If you have XP, try this!!! Go into a command prompt window and type "sfc/scannow". I'm not sure why, but XP will ask you to insert Whistler Professional or Whistler Home. even if you have already inserted it. Not only do they get the name wrong, dumbass XP doesn't recognize the fact that you have the disk in the computer already when it just read from it a second ago!!!
