Hey, well I know a way to sign into multiple MSN's at one time, try to install StuffPlug v3 (I'm not sure if it works with the new MSN Beta works fine with MSN plus though) Click the StuffPlug icon, click general I think it was in the Options, and click Polygami (Sorry for typo's) Then open MSN normally with your other MSN opened, it should open it and let you log in fine.
