Nomination for the Alberta

[DBat]

I know all you guys are astep ahead. but here I am having a peculiar situation.
I applied my AIPNP application in the month of April 14 2009.
Along with me 3 of my friend applied.

In the Month of the July I received the File No. And my friends received the after two months ie the file number.

After 5 all of my three friends received their nomination from Alberta Immigration. and Till now I did not.

I am unable to understand why I am unable to receive it.

When I changed my address I updateds in usps and also sent an email to them notifying the change of the address. I got reply from them saying that address change will matched to my application.
