Eject disc, power off, error message

Wii is 1 week old. Plays sports disc just fine. Just bought Mario super Galaxy. Get the eject disc, power off error message. Tried this several times and get the same message. Exchanged the game thinking it was the disc but still getting the same message.

Is there some magic you guys know of that can fix this or am I going to have to send it in like customer support is saying?
