Error with WordPress.com Stats plugin

Hey there everyone, hopefully I post this in the right place and in the right forum to begin with.

I have recently updated my WordPress.com Stats plugin and it asked me to deactive and then active my plugin once again for it to work and for me to successfully login and display the stats. I did this, and now I have received this error message after using the API code given to me on my WordPress.com profile:

“Error from last API Key attempt:

The owner of that API Key (garygomes) is not on the access list for this blog (2258324). To be added to the access list, you must contact support.”

How do I get this resolved?

Thanks everyone!
