Can not edit

I tried a new theme & I can not get to admin to edit my blog. Any help really appreciated. You can see it here. I did find this
Fatal error: Call to undefined function: bloginfo() in /homepages/38/d152307251/htdocs/mjrnow/wordpress-2.5.1/wordpress/wp-content/themes/3-column-pressrow-01/3-column-pressrow-01/header.php on line 5

Thanks
