I purchased an album using my itunes store account on this MacBook a couple of months back. Sadly the hard drive died on this machine so I had to replace and it and reinstall tiger. Itunes is recognizing this MacBook as a new machine which is understandable, however I would like to download that album again because it says I can on up to 5 of my macs. When I log into my itunes store account on this machine and go to the album it is asking me to buy it again. How do I get this album back?
