I-130 for sibling had RFE years ago, but I didnt file Change of Address

[lazy 19]

Hi there,

I filed I-130 for my sister and her husband years ago in Feb/March 2009, and then moved, and failed to file AR-11 Change of Address and proper mail forwarding at USPS.

Subsequently USCIS sent RFE for my sister in July 2009. Unfortunately I did not recieve it, nor was I aware nor did anything happen.

When I looked up the case number last week, it shows my sister with RFE status from July 2009 and "Case was received" for Bro-in-law from March 2009.

What am I supposed to do next?

Are these submissions of I-130 expired/dead? (the case status shows 1) RFE and 2nd) I-130 received)

Please advise.
