DV AOS I-485 Receipt received & waiting :0(

[caseno11k]

I filed my I-485 and have received the receipt. The recipt has a
MSC ******** (Missouri Service Center..?), which I cannot track online, I get this error

"Your case can not be found at this time in Case Status Online. Please check your receipt number and try again. If you need further assistance please call the National Customer Service Center at 1.800.375.5283.
" <<== This I figure is not uncommon, however it has been a month since the receipt and I have not received my appointment letter or anything else from the USCIS... I am freaking out as I have not filed for a H1B thinking that this would be quick.... any advice on how this works?

Is there a way to track my case at all?

if not,

Has anybody passed through a similar situation.. or knows approximately how long it takes to get the Biometrics/Interview letter to arrive on the mail from the date the receipt was sent ? (In my case March 13, 2009).

Please Help... I am all stressed out :0(
