Microsoft no nonger calls Essentials 2011 "beta" but from all the problems people have been reporting with it (especially Mail), I suspect it still is. Maybe that's why they named it "2011". Perhaps you should uninstall 2011 completely (including Mail) and go back to 2009. Note that the web version installers allow you to download just the programs you want within the package but it looks like you can't selectively upgrade some programs but not others:
