I have just recently upgraded the hard drive in my Macbook Pro, so I have to re-activate all of the content in my iTunes library so I can sync my 8gb ipod touch. But I also changed the email address and password that my iTunes account is using and it gives me the old email address to sync some of the apps. When I enter the either of the passwords and it's wrong and when I change the e-mail address to my current one it says its already authorized and prompts me again for the old email address. Is there any fixes for this situation? Thanks in advance!
