Wordpress plugin upgrade

I need of an upgrade of the Advanced Permalink Plugin: [login to view URL] This plugin is not working with wordpress 2.7.1 I must configure a custom permalink for specific posts. New permalink need to be like /%year%/%monthnum%/%postid%_%postname%.html startiong from a specific post_id ## Deliverables Actually this plugin return a 404 error when using custom permalink. And it add slash after configured custom permalink. The main porpouse is to have the possibility to choose a custom permalink stucture for posts starting from a defined id. Final permalink will look like a html page This plugin originally do what expected, but don't look to work with new version of wordpress It need to work with sitemap generator plugin (if well developed it will) Need a small documentation with modification and reasons
