Problems with my API and new blog (WP Stat Plugin)

Hi everyone!

I used to have a blog with own domain with WP Stats plugin installed and registered with my API Key. Works perfectly.

But the problem is that now I have no more this blog, but another, with another own domain. When attempting to install the WP Stats plugin on my new blog, I asked for API Key. But when I try to use it, I get the following error message:

“Failed attempt from last API Key:
The owner of that API Key (xxxxxxxx) is not on the access list for this blog. When this blog was registered, ‘s API key was used. To add you to the access list, must visit this blog’s dashboard stats page and use the form at the bottom of that page.”

The big point is: how can I change my domain on the dashboard? This function is not available for me… I can only view the URL for lod blog. There is no change as this.

Thanks for your time and help.

Greetings.
