Ever since went from XP to Windows 7, none of my contacts are ever online.  One happens to be my boss who I know for a fact is online every day since this is a faster way to communcate.  They use MSN messenger but Geek Squad told me windows live messenger is the same thing with a different name.  Never once have I seen one of my contacts on line.  Never had this problem when I had MSN Messenger.  Please Advise.
