Problems with self-hosted blog and WordPress Sitecounter

when installing the WordPress.com Stats v1.4 Plugin widget, it doesnt’ calculate total visitors.

And when I try to log into the wordpress.com stats it doesn’t do anything.

Another problem is that when I log into the self-hosted blog the global dashoboard in the top that provides access to all other blogs disappears. While wordpress features such as comments and whatnot work fine, I think some part of it may be installed incorrectly.
