WordPress.com stats Wrongly Shown

I was creating an independent wordpress blog with wordpress.com stats plugin installed.

However, when I transfered all of my blog data to another wordpress blog, I was encountering a problem when accessing wordpress.com stats.

Actually, I want two different stats. For example my first blog has 500 articles, and wordpress.com stats shows 10K Views, and my second blog has 500 articles + 200 new articles, but I did not get different views, but the same page views like the same.

So I uninstalled the wordpress.com stats and re-entered a different API Key. To my surprise, I got the following problem too.

Error from last API Key attempt:

The owner of that API Key (pressphrase) is not on the access list for this blog (13089703). Stats was installed using a different API key. The owner of the original key can add users to the access list, or you can contact WordPress.com support.

So I will have to make a post to seek help from community.

Thanks for your help in advance.
