I bought my MBP back in November and I'm just now registering the Applecare that I bought. It says I need to tell them my Applecare registration number, which should be located on the box it came in, which sounds all well and good...but I didn't receive a box. They just sent me a disc. I put the disc in but it had nothing helpful on it. All the support articles keep talking about finding the number on the box, but I don't have one. Help!
