Here is a link to the documentation that shows how to set up live writer
to work with Sitefinity.
In Live Writer you need to set the page on which you have BlogPostView control that shows your posts. Make sure that AllowBlogging
is set to true. Can you send some screenshots that shows BlogPostView control configuration ? Do you set ti to show specific blog, you have some filtering etc? Here is a short video
that shows the setup and blog post publishing with Live Writer 2011 build 15.5.3508.1109.
