How Do You Unregister Adobe CS2?

Anyone knows how to unregister Adobe Premium CS2? I had installed CS2 on my mac a while ago and registered it under my name. Then I removed CS2 from my mac (but didn't unregister it before removing it from my mac) and installed CS3 on the same mac. Now my mac has CS3 on it but how do I unregister CS2 which is still under my name but it's not on my computer anymore?
Thanks!

If you removed using the unistaller it is unregistered. If you are asking to sell CS2 and registering again in someone else's name, ask Adobe forums.

Thanks Harry.
Yes I want to unregister to sell it to someone.
Appreciate the help!

Just remember if this is an Education version of the software, it cannot be re-sold and registered again.
