Many people have tried the newer version of Movie Maker 2011 or 2012 and complained about the lack of a traditional timeline, issues with crashing, long times to prepare video files and the inability to customize the transitions, effects and titles. If you have been building up a library of custom titles, transitions and effects under Windows Movie Maker 6.0, none of these can be used in the newest Movie Maker because the rendering architecture has changed and Microsoft has no API for customizing things.
