I got an ipod touch a couple days ago, and along with it i got an album giftcard thing. So i set up itunes and downloaded the album, but I only wanted certain songs (i liked most but not all) and so i looked around to find something and eventually my itunes was not responding. I close it and open it, everything is gone. I was logged into my apple account, and the whole album was downloaded. So i decided to download it again. I typed in the code and it said "This code can be used only once". Any advice?
