Windows Live Mail 2011 Version Problems

I recently upgraded from Windows 7 to 10.  I have been using Windows Live Mail 2011 for years with no problems.  Now all of a sudden whenever I try to get email, a pop up asking for my user name and password comes up and when I x out of it because my name and password are already saved there, a notice that I can't receive or send email because of incorrect password comes up.  It says account is locked by another session or for maintenance.  Try again.  I've called my web mail provider (time warner cable) and the problem is not with their server.  My settings are on POP3 server.  Do I need to now be on IMAP for Windows 10?  It doesn't give me the option to click on anything but POP.  Not sure what to do and very frustrating to not be able to get email on my windows live program.  Can someone please help?  Thank you.
