I140 AN is rreturn to CIS

My I140 is approved on Jan 3,05. I didn't received notice, but today i received the email as following:

Application Type: I140 , IMMIGRANT PETITION FOR ALIEN WORKER

Current Status:

Our last written notice in this case was returned as undeliverable by the post office on January 17, 2005. To update the mailing address so this notice can be re-sent, please call the National Customer Service Center at [phone].

Neither my home address nor my lawyer's address has been changed since filing.

My questions are
1) Which address will CIS send notice to for I140? my home address, my lawyer or my company?
2)Does this affect I485 processing?
3) Should I or my lawyer to call CIS to see what is worng?

Thanks.
