How do I get authorization code for an expired domain?

I have a Yahoo!® domain that expired over a month ago ;-((( My "new" registrar says "I need to get an 'Authorization Code'."

These links should help you find your answer:

once the site is expired...

as i know we cannot log into domain control panel,

so we cant do anything about getting auth code to transfer http://answers.yahoo.com/question/accuse_write?qid=20080225231537AA2nvSV&kid=F8BxM2fuAnXCQUOHJSec&s=comm&date=2008-04-24+06%3A41%3A03&.crumb=
