It could be taken a week or longer to review your file.
You did track your package and was delivered successfully to the NVC.
Then you don't need to worry about it might be lost.
The operator only can tell you the result once someone finishes reviewing your DS230.
Before that, they only tell you not receive it yet or no any update.
Because their system can't see any information until someone types your file into their system.

I think you should fill a new form and sign by the visa beneficiary.
I sent my IV packet and my husband sent his to the NVC.
But I also sent some blank forms and I pre-signed on the forms
just for in case.

You skip too far.
You have to finish your NVC stage.
1.AOS-I864 bill&packet
2.IV-DS230 bill&pakcet
3.medical exam

You can send DS3032 by email right now and wait for a week to be accepted by NVC.
No attach no sign no form only an email. I did it and most people did the same way no problem.
Then you pay for your AOS bill when it's invoiced.
After you pay for the bill and it shows as PAID, you can print barcode coversheet out.
Submit the bardcode coversheet with your I864 form and supporting document.
Because at your first post, you wrote" Whats next after that ? waiting for the interview date ?" That's why I said you skip too far.
can't pay AOS bill? is it invoiced yet? Are you using Internet explorer browser? only IE can process the bill.
DS230=immigration visa application is a form for the Green card beneficiary to fill and sign it.
http://travel.state.gov/visa/forms/forms_1342.html
DS230=IV bill is invoiced after DS3032 is accepted.
No DS3032 acceptance no IV bill invoice.
Now, can you understand what I say?

I've been following following links and VJ threads in general from day 1. They have been great help.
http://www.visajourney.com/wiki/index.php/How_Do_I_Bring_My_Spouse_%28Husband_or_Wife%29_to_Live_in_the_United_States%3F
There is also a few shortcut threads but not much different.
1) http://www.visajourney.com/wiki/index.php/James%27s_Shortcuts
2) http://www.visajourney.com/wiki/index.php/LingChe_NVC_ShortCut
They are all very similar and explain everything you need to know.
Like anyone on VJ will tell you, READ AND RESEARCH BEFORE YOU DO ANYTHING.
Feel free to send me any questions you have.

I just paid my AOS bill too, this great as it will save us a lot of time
