activation

hi just wondering if i can switch my norton 2010 antivirus as i bought it for my old computer which crashed exactly 3 days after activating it. now i've bought a new one but am faced with having to buy another one for $30 if i can't figure some way to reactivate it to my new computer.

if anyone could help i'd greatly appreciate it as i can't find an email address to send my query to,

cheers
