3.2.1 update broken Windows Livewriter template width

I have been using Windows Live Writer for many years without any problems. However, since the update to wordpress 3.2.1 I am finding that my Windows Live Writer has completely lost my template width and seems to make a mess of all my posts.

I have reinstalled my theme (created using artisteer) and have deleted my blog account from livewriter and reinstalled it… I have also selected to update my blog theme in Livewriter which downloads succesfully. However, it simply has no idea about the width.

Help please as I do not want to have to write posts from the dashboard!
