Mountain lion says i don't own it
I recently purchased a MacBook Pro 15 inch 2012 from the apple store; and i was told that mountain lion would now be registered to my account. I looked today because i decided to see what was new in mountain lion compaired to Lion (Which was on my old macbook). But when i looked, yea i could read mountain lion's features, but it isn't registered to me. As in if i wanted to resotre my own system, i'd have to pay for mountain lion again. How can i fix this?
MacBook Pro, OS X Mountain Lion (10.8.3)
