Windows Live Mail 2011 is my e-mail client.  I created a group contact list in my Contacts folder.  It appears there.  But, when I try to send an e-mail to the group contact list, the response is "No matches found."  Then: "The message could not be sent.  One or more recipients do not have an email address.  Please checkyour Contacts and make sure all the recipients have a valid email address."  I checked, and all do have valid email addresses.  Also: when I double-click on "To" or "CC" or "BCC," my Contacts list comes up---but the group contact list doesn't show.  Please help.  Thanks.
