i Need Help

De-authorise all computers (in the iTunes Store) and then authorise only the ones you want.

By the way, this is a forum, not a chat room. Your first post; "I need help" is unlikely to get you any help, since it provides no information at all for anyone to comment on. Furthermore, posting a another thread just 14 minutes later and then following that up in just one minute is actually quite rude. Please remember that this is a worldwide forum. There may only be one or two people who know how to help you, but if they're on the other side of the world to you, they may not going reply for several hours. Even longer sometimes.
