my i-485 timeline and helppp

[enoch 0]

I need some help.

Here is my timeline:

08/06/2010 - Mailed to Chicago office Express Mail (i485, i485a, i864, i765, i131 etc.)

08/09/2010 - Received by Chicago USCIS Chicago Express.

08/18/2010 - Checks cashed

08/21/2010 - NOA's received in the mail

but yesterday I got a mail from the US Dept of State National Visa Center saying that I need to pay the AOS (Affadavit of Support Fee) of $88 and

two things they note:

1.If the applicant intends to adjust status with the USCIS, please contact the NVC before making any payments or taking further action.

2. Children who pass 21 years of age after the petition was originally approved by the USCIS become ineligible to accompany or join the applicant immigrating to the US under the original petition. In some sitations, the CSPA may allow children to remain eligible beyond 21 years of age. If you believe that the CPSA applies to this case, please send a detailed explanation to the NVC. We will forward it to the U.S Embassy/Consulate General for a decision.

My brother and I are beneficiaries of the CSPA and my lawyer submitted CSPA noted letters with our i485, i485a, i864, i765, i131 etc. package when we mailed it to the Chicago Office.

I contacted my lawyers office but hes out of the country til after labor day. Any advice how to proceed?
