I had this same problem with my other blog. This time it is on my main site- http://multipleverses.com
I installed Jetpack and had to disable it because it did not allow me to use my visual editor. When I removed Jetpack- my wordpress.com stats plugin would not work. I get the error that I do not have access to my askimet key and am not an authorized user of it even though I have askimet up and running no problem on my blog.
