having trouble authoizing another computer
I downloaded a few movies and apps on my son's iPad (iPad 1). It has been awhile since I have synced the iPad and computer. So I am kinda out of practice. Anyway.I have a new computer, I wanted to sync what is on his iPad onto my computer (trasnfered it in case he looses apps etc) that way I can just transfer it back to iPad from computer. Since my computer is new do I have to authorize it before. If so how do I do this I looked up on help but what it said is not working. My son uses his computer for school ,he is special needs.
iPad, Windows XP
