Original Title: Mr

Recently when opening my Windows Live Mail  I have been getting a window requesting to enter my user name and password even though my Windows live Mail is already open.  However thinking that it was a legitimate request I entered both user and passwords only to be rejected as not correct.  I then tried entering an older password only as my user name has never change and yet again it was rejected.  As my windows live mail was open I carried on using and ignored and deleted the request window and everything worked ok.  This still happens every time I open my e-mail and more recently I have been receiving "Mail Delivery Failure " notifications regarding e-mails that I have not sent and when I look into the details they are e-mails that have been sent to old contact addresses

that have not been in use for a very, very long time possibly since the days of an older computer which when I replaced I destroyed  the Hard Drive completely before disposal.    can anyone help with a possible solution to this annoyance or should I uninstall Windows Live Mail to try to clear and then re-install.
