Stats Page is not showing

Hi everyone, I’ve been hosting a WP blog on my own server. Installed the WP-stats and it’s just now showing how many visitors I have correctly. I have got another blog with WP host called didastudio.wordpress.com and my self-hosting blog is

http://www.didastudio.co.uk

I’ve used the API key provided for my WP hosted blog for the self-hosted blog and have clicked replace the blog. But it’s still not showing. Does anyone know what had gone wrong?

Thanks!
