wordpress.com stats error

I added wordpress.com stats to my new blog crazybulb.com, after entering API key I chose option ‘Replace an existing blog’ replaced priceblog.net by new blog. now i wanted to change and ‘Add new blog to my account’ so i reentered the API key and selected ‘Add new blog to my account’ but its showing me following error. BTW I have also changed wordpress.com account from ‘princesinghania’ to ‘saurabhdidwania’

I saw:
Error from last API Key attempt:

The owner of that API Key (saurabhdidwania) is not on the access list for this blog (9097987). To be added to the access list, you must contact support.

I want to separate stats for both crazybulb.com and princeblog.net

HELP plz!!!!
