I just had to reinstall windows because of a nasty infection. I had all my songs on my iPhone so I could load them when I reinstalled iTunes. I proceeded to go to files then to tranfer purchases from iPhone. When I did that a warning came up saying this computer wasn`t authorized to play about 100 of my songs and to go to the store and authorize my computer. Which I did. So I gave it another try but the same message came up. I went back to authorize it again and it said this computer is authorized. What gives? Anyone incounter this problem and if so, how do I fix it. Thank you.
