OK, my combodrive on my Macbook is broken. Wont play CDs/DVDs, just spits them out after about 20 seconds or so. I bought Applecare with my Mac back in September 2006 so I guess I'm covered, do I just take the receipt with me to the Genius Bar when I see them later today? I have the box thing that you got but never loaded the provided CD or registered online. Help take some pressure off my back please!
