i'm trying to set up my nabaztag/tag, and when i get to the stage of setup where all his lights turn green, he keeps all four lights green, including a green base, rotates his ears...and then dies. turns off, goes white, totally unresponsive. the base never does turn purple. why does he keep dying? do i have a suicidal rabbit on my hands? help me make him stay alive and connected, please!
