Hi just got my new laptop and added my backed up library, i have authorised my itunes purchases to play on the new laptop but it is saying that i have 3 computers authorised to play them, my last laptop was stolen and im sure i deauthorised my first pc but i cant have.

Is there anyway to authorise the purchases to play on my new laptop only? im usually good with itunes but im stumped here.

Help would be appreciated thanks

The option to "Deathorize All" only appears when five computers have been authorised. So, if need be, authorise two more then choose this option and then re-authorise the ones you want to play Fairplay-encumbered content on.
