Godaddy installation

I’ve tried searching these forums for an answer to this problem to no avail.

I set up a wordpress.com blog and then mapped a godaddy domain to the blog. All well and good.

But I decided to change to a self managed ww.wp.xz.cn blog, and thus purchased the godaddy wordpress hosting package.

I installed wordpress on the domain and got an email saying that the installation was successful, but when i log into [blogname].com/wp-admin it is still the dashboard for the wordpress.com site, rather than ww.wp.xz.cn.

All i want to do is use my godaddy domain with a ww.wp.xz.cn installation. Given that I have purchased godaddy’s wordpress hosting, how do I go about this?

Any help much appreciated 🙂
