my apple id dont authorised plz help

These are user-to-user forums, you are not talking to Apple here - I've asked the hosts to remove your account id from your post.

If you have reached the 5 computer limit (the limit can't be rasied) then you can individually deauthorise computers directly on them (via the Store > Deauthorise This Computer menu option), or you can log into your account on your computer's iTunes (Store > View My Account, Store > View My Apple ID on iTunes 11) and 'deauthorise all' (which you can do once every 12 months) and you can then authorise/reauthorise the computers that you still have and need : authorising and deauthorising.

If can't access your computers to individually deauthorise them and if you've already done 'deauthorise all' during the past 12 months then you can try contacting iTunes support and see if they deauthorise them for you : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
