I have a similar problem. WordPress.com Stats plugin will not accept my API key. Error messages are:-
Error from last API Key attempt:
Missing API Key
The WordPress.com Stats Plugin is not working because it needs to be linked to a WordPress.com account.
Enter your WordPress.com API key to link this blog to your WordPress.com account. Be sure to use your own API key! Using any other key will lock you out of your stats. (Get your key here.)
So I enter the API key and click on SAVE
NEXT MESSAGE
The API key “xxxxxxxxxxx” belongs to the WordPress.com account of “wuyihealthtea”. If this is not your account, please re-enter your API key.
Re-enter API key
According to the WordPress.com database, this API key is already associated with at least one self-hosted blog. You can add this as a new blog on your WordPress.com account or replace an existing blog and inherit its stats history.
Add new blog to my account
Do this if this blog is new or has never been associated with your API key. This blog will be added to your WordPress.com account.
Add to WordPress.co account
So I click on Add to WordPress.com account.
Then it’s back to the missing API Key error message -it just loops.
Error from last API Key attempt:

No matter how many times I enter the API key it does recognize I’ve entered it.
Can someone tell me what I need to do to get Stats up and running. I’ve searched support forums and find others with similar problems whose questions appear to go unanswered.
I did find a post which gave me hope, it referred to changing the API key. I tried the suggestion, however, when I follow the instructions I do not see the “Stats Access” area at all.

If I am unable to get WordPress Stats working is there any other alternative?
I’d be grateful for any assistance. Thank you. Judi
