I upgraded to Windows 10 and tried it out for a couple of days.  I restored an image of my earlier Windows 7 on the disk.  Now WIndows Live Mail wants username/password when it is opened but won't accept my username/password, with the message that Windows Live Mail is locked with too many logins.  Is this a result of having used Windows 10?  How can I regain access to Windows Live Mail using Windows 7?
